Abstract--- The detection of moving object is an important in many applications such as a vehicle identification in a traffic monitoring system,human detection in a crime branch.In this paper we identify a vehicle in a video sequence.This paper briefly explain the detection of moving vehicle in a video.We introduce a new algorithm BGS for idntifying vehicle in a video sequence.First, we differentiate the foreground from background in frames by learning the background.Then, the image is divided into many small nonoverlapped frames. The candidates of the vehicle part can be found from the frames if there is some change in gray level between the current image and the background.The extracted background subtraction method is used in subsequent analysis to detect a vehicle and classify moving vehicle.

Transportation Systems (ITS). Traffic Surveillance System is being more and important with improving
urban scale and increasing number of vehicles. This Paper presents an intelligent sign board
classification method based on blob analysis in traffic surveillance. Processing is done by three main
steps: moving object segmentation, blob analysis, and classifying. A Sign board is modelled as a
rectangular patch and classified via blob analysis. By processing the blob of sign boards, the meaningful
features are extracted. Tracking moving targets is achieved by comparing the extracted features with
training data. After classifying the sign boards the system will intimate to user in the form of alarms,

Real Time Object Identification for Intelligent Video Surveillance ApplicationsEditor IJCATR
Intelligent video surveillance system has emerged as a very important research topic in the computer vision field in the
recent years. It is well suited for a broad range of applications such as to monitor activities at traffic intersections for detecting
congestions and predict the traffic flow. Object classification in the field of video surveillance is a key component of smart
surveillance software. Two robust methodology and algorithms adopted for people and object classification for automated surveillance
systems is proposed in this paper. First method uses background subtraction model for detecting the object motion. The background
subtraction and image segmentation based on morphological transformation for tracking and object classification on highways is
proposed. This algorithm uses erosion followed by dilation on various frames. Proposed algorithm in first method, segments the image
by preserving important edges which improves the adaptive background mixture model and makes the system learn faster and more
accurately. The system used in second method adopts the object detection method without background subtraction because of the static
object detection. Segmentation is done by the bounding box registration technique. Then the classification is done with the multiclass
SVM using the edge histogram as features. The edge histograms are calculated for various bin values in different environment. The
result obtained demonstrates the effectiveness of the proposed approach.

Proposed Multi-object Tracking Algorithm Using Sobel Edge Detection operatorQUESTJOURNAL
ABSTRACT:Tracking of moving objects that is called video tracking is used for measuring motion parameters and obtaining a visual record of the moving objects, it is an important area of application in image processing. In general there are two different approaches to obtain object tracking: the first is Recognition-based Tracking, and the second is the Motion-based Tracking. Video tracking system raises a wide possibility in today’s society. This system is used in various applications such as military, security, monitoring, robotic, and nowadays in dayto-day applications. However the video tracking systems still have many open problems and various research activities in a video tracking system are explores. This paper presents an algorithm for video tracking of any moving targets with the uses of contour based detection technique that depends on the sobel operator. The proposed system is suitable for indoor and outdoor applications. Our approach has the advantage of extending the applicability of tracking system and also, as presented here improves the performance of the tracker making feasible high frame rate video tracking. The goal of the tracking system is to analyze the video frames and estimate the position of a part of the input video frame (usually a moving object), our approach can detect, tracked any object more than one object and calculate the position of the moving objects. Therefore, the aim of this paper is to construct a motion tracking system for moving objects. Where, at the end of this paper, the detail outcome and result are discussed using experiments results of the proposed technique
An Innovative Moving Object Detection and Tracking System by Using Modified R...sipij
The ultimate goal of this study is to afford enhanced video object detection and tracking by eliminating the
limitations which are existing nowadays. Although high performance ratio for video object detection and
tracking is achieved in the earlier work it takes more time for computation. Consequently we are in need to
propose a novel video object detection and tracking technique so as to minimize the computational
complexity. Our proposed technique covers five stages they are preprocessing, segmentation, feature
extraction, background subtraction and hole filling. Originally the video clip in the database is split into
frames. Then preprocessing is performed so as to get rid of noise, an adaptive median filter is used in this
stage to eliminate the noise. The preprocessed image then undergoes segmentation by means of modified
region growing algorithm. The segmented image is subjected to feature extraction phase so as to extract
the multi features from the segmented image and the background image, the feature value thus obtained
are compared so as to attain optimal value, consequently a foreground image is attained in this stage. The
foreground image is then subjected to morphological operations of erosion and dilation so as to fill the
holes and to get the object accurately as these foreground image contains holes and discontinuities. Thus
the moving object is tracked in this stage. This method will be employed in MATLAB platform and the
outcomes will be studied and compared with the existing techniques so as to reveal the performance of the
novel video object detection and tracking technique.
A NOVEL BACKGROUND SUBTRACTION ALGORITHM FOR PERSON TRACKING BASED ON K-NN csandit
Object tracking can be defined as the process of detecting an object of interest from a video scene and keeping track of its motion, orientation, occlusion etc. in order to extract useful
information. It is indeed a challenging problem and it’s an important task. Many researchers are getting attracted in the field of computer vision, specifically the field of object tracking in video surveillance. The main purpose of this paper is to give to the reader information of the present state of the art object tracking, together with presenting steps involved in Background Subtraction and their techniques. In related literature we found three main methods of object tracking: the first method is the optical flow; the second is related to the background subtraction, which is divided into two types presented in this paper, and the last one is temporal
differencing. We present a novel approach to background subtraction that compare a current frame with the background model that we have set before, so we can classified each pixel of the image as a foreground or a background element, then comes the tracking step to present our object of interest, which is a person, by his centroid. The tracking step is divided into two different methods, the surface method and the K-NN method, both are explained in the paper.Our proposed method is implemented and evaluated using CAVIAR database.

Vehicle Tracking Using Kalman Filter and Featuressipij
Vehicle tracking has a wide variety of applications. The image resolution of the video available from most traffic camera system is low. In many cases for tracking multi object, distinguishing them from another isn’t easy because of their similarity. In this paper we describe a method, for tracking multiple objects, where the objects are vehicles. The number of vehicles is unknown and varies. We detect all moving objects, and for tracking of vehicle we use the kalman filter and color feature and distance of it from one frame to the next. So the method can distinguish and tracking all vehicles individually. The proposed algorithm can be applied to multiple moving objects.
A New Algorithm for Tracking Objects in Videos of Cluttered ScenesZac Darcy
The work presented in this paper describes a novel algorithm for automatic video object tracking based on
a process of subtraction of successive frames, where the prediction of the direction of movement of the
object being tracked is carried out by analyzing the changing areas generated as result of the object’s
motion, specifically in regions of interest defined inside the object being tracked in both the current and the
next frame. Simultaneously, it is initiated a minimization process which seeks to determine the location of
the object being tracked in the next frame using a function which measures the grade of dissimilarity
between the region of interest defined inside the object being tracked in the current frame and a moving
region in a next frame. This moving region is displaced in the direction of the object’s motion predicted on
the process of subtraction of successive frames. Finally, the location of the moving region of interest in the
next frame that minimizes the proposed function of dissimilarity corresponds to the predicted location of
the object being tracked in the next frame. On the other hand, it is also designed a testing platform which is
used to create virtual scenarios that allow us to assess the performance of the proposed algorithm. These
virtual scenarios are exposed to heavily cluttered conditions where areas which surround the object being
tracked present a high variability. The results obtained with the proposed algorithm show that the tracking
process was successfully carried out in a set of virtual scenarios under different challenging conditions.

High Speed Low-Power Viterbi Decoder Using Trellis Code ModulationMangaiK4
Abstract - High speed low power viterbi decoders for trellis code modulation is well known for the delay consumption in underwater communication. In transmission system wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor. WiMAX is the wireless communication standard designed to provide 30 to 40 Mega bits per second data rates. WiMAX as a standards based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL. WiMAX can provide at home or mobile internet access across whole cities or countries. The address generation of WiMAX is carried out by interleaver and deinterleaver. Interleaving is used to overcome correlated channel noise such as burst error or fading. The interleaver/deinterleaver rearranges input data such that consecutive data are spaced apart. The interleaved memory is to improve the speed of access to memory. The viterbi technique reduces the bit error rate and delay using wimax.

Extraction of heterogeneous entities from biomedical documents is being a big challenge as achieving high f-score is still a problem. Text Mining plays a vital role for extracting different types of entities and finding relationship between the entities from huge collection of biomedical documents. We have proposed hybrid approach which includes a Dictionary based approach and a Rule based approach to reduce the number of false negatives and the Random Forest Algorithm to improve f-score measure.
Saturation Throughput and Delay Aware Asynchronous Noc Using Fuzzy LogicMangaiK4
Abstract-Due to scaling in recent trends in modern semiconductor industries, critical instance such as voltage spikes, temperature, interlink between IC circuits has been improvised under the design. The saturation throughput and average message delay are used as performance metrics to evaluate the throughput. We introduced the fuzzy logic based asynchronous NoC to attain the high throughput and diminish the delay between the inter logic circuits aim to select the less congested paths to produce load balance in the network especially under realistic traffic loads. Our Fuzzy logic based routing algorithm is an adaptive, low cost, and scalable. It outperforms against different adaptive routing algorithms in the average delay and saturation throughput for various traffic patterns. STDR can achieve up to 12%–32% average message delay lower than that of other routing algorithms. Moreover, the proposed scheme yields improvements in saturation throughput by up to 11%–82% compared with other adaptive routing algorithms
Abstract - A password is a sequence of characters used to determine whether the user is authenticated or not. Nowadays most of the password is text-based. Since text based password is hard to remember people try to use simple memorable password such as pet names, phone number, etc. which are easy to break by intruders. The main idea behind the paper is to replace the text-based passwords by image based password and encrypt using RSA algorithm. Our experimental result shows that image passwords are easy to remember, better than the text.
A Framework for Desktop Virtual Reality Application for EducationMangaiK4
Abstract: Contemporary custom in education encourages students to gain exposure in the real world through student visits (field visits) to sites in count to conventional textbooks and lectures. This disclosure helps students to experience real world situations and integrate this experience into knowledge learned in class. This is important to students in various disciplines such as engineering, architecture and transportation. Students, however, have limited on-site access due to issues related to safety concerns, cost and effort. In an attempt to address such issues, Virtual Reality (VR) applications have been developed and implemented. With the growth in the number of VR applications, there is currently a lack of information about the design issues of VR applications from the standpoint of integrating different types of information associated with the real world. This paper aims to bridge this gap by evaluating VR applications with respect to these issues and highlights the lessons learned from the appropriate evaluations. The results demonstrate that VR application, which links different sources of information (as developed in this paper), promotes better learning than conventional printed materials and that students professed it positively as a precious complement to a physical field visit. The design recommendations for the development of similar VR learning applications are further discussed in this paper.

BugLoc: Bug Localization in Multi Threaded Application via Graph Mining ApproachMangaiK4
Abstract - Detection of software bugs and its occurrences, repudiation and its root cause is a very difficult process in large multi threaded applications. It is a must for a software developer or software organization to identify bugs in their applications and to remove or overcome them. The application should be protected from malfunctioning. Many of the compilers and Integrated Development Environments are effectively identifying errors and bugs in applications while running or compiling, but they fail in detecting actual cause for the bugs in the running applications. The developer has to reframe or recreate the package with the new one without bugs. It is time consuming and effort is wasted in Software Development Life Cycle. There is a possibility to use graph mining techniques in detecting software bugs. But there are many problems in using graph mining techniques. Managing large graph data, processing nodes with links and processing subgraphs are the problems to be faced in graph mining approach. This paper presents a novel algorithm named BugLoc which is capable of detecting bugs from the multi threaded software application. The BugLoc uses object template to store graph data which reduces graph management complexities. It also uses substring analysis method in detecting frequent subgraphs. The BugLoc then analyses frequent subgraphs to detect exact location of the software bugs. The experimental results show that the algorithm is very efficient, accurate and scalable for large graph dataset.

This method is suitable for various applications uses images like remote sensing, medical and Spatio-temporal.
A Review on - Data Hiding using Cryptography and SteganographyMangaiK4
Abstract - Security and privacy for a data transmission become a major concern due to rise of internet usage. Many developers are working continuously to make an internet safe environment, but the intruders are very smart to hack the information. For that, two entities communicating need to communicate in a way which is not susceptible to listen in or interception. So every organization uses many data encryption techniques to secure their communication. There are two security mechanisms called, Cryptography and Steganography are being applied. By merging these techniques, two level of information security is achieved. This paper discuss about the way of working Cryptography and Steganography and their different approaches.
Modeling Originators for Event Forecasting Multi-Task Learning in Mil AlgorithmMangaiK4
Abstract - Multiple-instance learning (MIL) is a speculation of supervised learning which tends to the order of bags. Like customary administered adapting, the greater part of the current MIL work is proposed in light of the suspicion that a delegate preparing set is accessible for a legitimate learning of the classifier. To manage this issue, we propose a novel Sphere-Description-Based approach for Multiple-Instance Learning (SDB-MIL). SDB-MIL takes in an ideal circle by deciding a substantial edge among the examples, and in the meantime guaranteeing that every positive sack has no less than one occasion inside the circle and every negative bags are outside the circle. In genuine MIL applications, the negative information in the preparation set may not adequately speak to the dispersion of negative information in the testing set. Thus, how to take in a proper MIL classifier when a delegate preparing set isn't accessible turns into a key test for genuine MIL applications. From the viewpoint of human examiners and approach producers, determining calculations must influence precise expectations as well as give to sup porting proof, e.g., the causal components identified with the occasion of intrigue. We build up a novel different example learning based approach that mutually handles the issue of recognizing proof based originators and conjectures occasions into what's to come. In particular, given a gathering of spilling news articles from different sources we build up a settled various occurrence learning way to deal with figure noteworthy societal occasions, for example, protests. Substantial investigates the benchmark and true MIL datasets demonstrate that SDB-MIL gets measurably preferable arrangement execution over the MIL strategies thought about.
Abstract: The common challenge for machine learning and data mining tasks is the curse of High Dimensionality. Feature selection reduces the dimensionality by selecting the relevant and optimal features from the huge dataset. In this research work, a clustering and genetic algorithm based feature selection (CLUST-GA-FS) is proposed that has three stages namely irrelevant feature removal, redundant feature removal, and optimal feature generation. The performance of the feature selection algorithms are analyzed using the parameters like classification accuracy, precision, recall and error rate. Recently, an increasing attention is given to the stability of feature selection algorithms which is an indicator that requires that similar subsets of features are selected every time the algorithm is executed on the same dataset. This work analyzes the stability of the algorithm on four publicly available dataset using stability measurements Average normal hamming distance(ANHD), Dices coefficient, Tanimoto distance, Jaccards index and Kuncheva index.

Renewable Energy Based on Current Fed Switched Inverter for Smart Grid Applic...MangaiK4
Abstract - Renewable energy is used in the current fed switched inverter for high power production. High voltage support, wide yield ranges of operation, shoot-through resistance are a portion of the desired properties of an inverter for a reliable, versatile and less ripple AC inversion. This paper proposes a single stage, high boost inverter with buck-boost capacity which has a few particular advantages over traditional voltage source inverters (VSI) like better EMI noise, wide input and output voltage range of operation, and so on. The proposed inverter is named as Current-Fed Switched Inverter (CFSI). A renewable energy based converter structure of CFSI has been created which supplies both AC and DC loads, at the same time, from a single DC supply which makes it reasonable for DC smart grid application. This paper proposes the operation and control of a CFSI based converter which directs the AC and DC conversion voltages at their reference. The advancement of the proposed converter from essential current fed DC/DC topology is explained. The closed loop controller is verified by using the MATLAB/ Simulink environment.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

I. INTRODUCTION
Now a days the growth of vehicle in a road has necessary
thing.Identification of moving vehicle in a video plays an
important role in many applications such as traffic monitoring
system,accident detection,reduce congestion and finding
ambulance vehicle.The first step of finding the moving vehicle
is to take a video sequence.For that purpose we fix a camera on
a signal.It take a sequence of video.Videos are sequence of
images.Each image is called a frame.An image is divided into
two parts.First one is the background image and another is a
foreground.We planned a method BGS to finding the
foreground of an image. The paper is organized as
follows:Section II describes in brief motion detection
architecture and its approaches.Section III covers the object
detection methods.Section IV Describes comparative study of
object recognition methods. Section V introduces a BGS
Method.Section VI explain the proposed work.In Section VII
Decribes experimental results. Finally, we conclude with a
discussion in Section VIII.
II. OBJECT DETECTION
Object identification is performed to existence of items in video
and to accurately locate that object. Most visual surveillance
systems start with movement identification. Movement
recognition aims at segmenting regions corresponding to
moving objects from the rest of an image. Object detection is to
establish a relationship between objects or object parts in
successive frames and to extract sequential information about
objects such as path, posture, speed and direction. The detection
of moving object's area of adjust in the same image sequence
which captured at different intervals in a video[5]. In reality,
road traffic can be broadly classified into two categories,
identical and varied. Detected objects frame by frame in video
is a important and difficult task. It is a crucial part of
monitoring systems since without object track, the system could
not take out interrelated sequential information about objects
and higher level performance analysis steps would not be
possible. Moving object detection is the first step in video
analysis. It can be used in many regions such as traffic
monitoring and face tracking.
III. OBJECT DETECTION METHODS
Object Detection
Temporal Differencing
Frame Differencing
Optical Flow
Background Subtraction
Temporal Difference Method
Temporal Differencing is based on frame differentiation which
attempts to detect moving regions by making use of the
difference of continuous frames (two or three) in a video series.
This method is highly adaptive to fixed background. So, the
temporal difference is a simple method for detecting moving
objects in a fixed background. But if the environment is not
static, the temporal difference method will very sensitive to any
movement and is difficult to differentiate the accurate and false
movement. So the temporal difference method can only be used
to detect the possible object moving area which is for the
optical flow calculation to detect real object movement.[3] . It
has high flexibility with active changes. Temporal differencing
technique utilize the pixel-wise variation between two or three
successive frames in a video imagery to take out moving
regions from the background [2]. It has high flexibility with
active scene changes although it cannot mine all related pixels
of a foreground image mostly when the object moves slowly or
has consistent surface [3, 4].When a foreground object is not
moving, temporal differencing method cannot detect a change
between successive frames and it lose the detection of item.
Frame Differencing
Frame differencing is a pixel-wise differencing between two or
three consecutive frames in an image sequence to detect regions
corresponding to moving object such as human and vehicles.
The threshold function determines change and it depends on the
speed of object motion. If the speed of the object changes much,
then it’s difficult to maintain the quality of movementation. The
inter-frame differencing approach detect parts of moving
objects by compare two consecutive frames. But, it can identify
only differences in the background environment and, for that
reason,it detects only parts of a vehicle covering the background
in the previous frame. Despite some enhancing techniques this
approach cannot acceptably deal with reasonable traffic
conditions where vehicles might stay still for a long time.[1].
Optical Flow
In this method ,the pattern of clear motion of objects, surface
and boundaries in a video caused by the relative motion

between an viewer and the scence.To detect moving regions in
an image, optical flow [5] uses flow vectors of the moving
objects over time. It is used for motion-based segmentation and
tracking applications. It is a dense field of dislocation vectors
which defines the change of each pixel area. Optical flow is best
suited in occurrence of camera movement, but however most
flow calculation methods are computationally very complex and
responsive to noise.
IV. COMPARATIVE ANALYSIS OF OBJECT
DETECTION METHODS
In this section we analyze the previously discussed different
vehicle detection algorithms.Table I indicate the evaluation of
these techniques on the basis of different advantages and
disadvantages.By analyzing these algorithms we concluded that
background subtraction method(BGS) is far better than
others.BGS method is greater uses rate of detecting vehicles.
V. BGS METHOD
BGS Method
Background elemination is a technique for finding a foreground
object from its background. It also known as Foreground
Detection. Background elemination method describe the recent
image is subtract from a reference background image, which is
upgrad during a period of time. It works well only in static
cameras. The elemination leaves only non-static or new objects,
which include whole dark region of an object. This approach is
simple and computationally affordable for real-time systems,
but it is very sensitive to active vehicle changes from lightning
and irrelevant event etc. Therefore it is highly reliable for good
background maintenance model.[6] The problem with
background subtraction [8], [9] is to automatically update the
background from the input video frame and it should be able to
overcome the following problems:
Movement in the background: Dynamic background
regions, such as lanes in a road,leaves and branches of
trees, or flowing water, should be recognized as part of the
environment.
Illumination changes: The background model should be
capable of slow changes in light over a phase of time.
Memory: The background module should not use much
resource, such as computing time and memory.
Gloom:Gloom cast by moving object should be identified
as part of the background and not foreground.
Mask: Moving object should be detected even if pixel
uniqueness are similar to those of the background.
Bootstrapping: The background model must be maintained
even in the lack of instruction foreground object.
VI. PROPOSED WORK
BGS method is a technique for identifying vehicles on a road.In
this algorithm a pixel is marked as foreground
If [Cf(x,y) – Bf(x,y)] > T (1)
In this equation where Cf is the current frame,Bf(x,y) is the
background frame and T is the predefined threshold value.
After the background frame Bf(x,y) is obtained, subtract the
background frame Bf(x,y) from the current frame Cf(x,y). If the
pixel difference is greater than the set threshold value T, then
determines that the pixels occur in the moving vehicle,
otherwise, it is consider as the background pixels. The moving
vehicle can be detected after applying threshold operation . Its
expression is given below:
Df(x,y)=1 if difference is grater than T,Otherwise 0
Where Df(x,y) is the binary frame of different results,T is
dynamic which will be identified depends upon environment
changes.Therefore,we add a dynamic threshold ∆T to the
vehicle detection BGS method.It is expressed as
∆T = λ ∗
1
M ∗ N
∑ ∑ [C(i, j) − B(i, j)] (2)
M
j=1
N
i=1
In equation 2 ,where M x N is the size of each image, ΔT
reflects the overall changes in the environment.
Then,
Df(x,y)=1 if difference is grater than (T+ ∆T),Otherwise 0
It is effectively eliminate the impact of light changes.
BGS method follows four steps namely caputuring the input as
.avi file, perform preprocessing(morphological
operations),foreground identifying,vehicle detection. The
sematic flow diagram of the proposed method is shown in
figure I
Step 1:Caputuring the Input
Read the .avi file using VideorReader.The input video file
converted into images to detect vehicle.These images are
gathered into frames.Create the frame to each images.This
process will be continued for all the frames.
Step 2:Morphalogical Preprocessing
The input image undergoes a series of morphological
operations to detect the exact shape of the
object.Morphological image processing is a collection of non-
linear operations related to the shape or morphology of features
in an image. Morphological operations can also be applied to
greyscale images. It can be used in pre or post processing
(filtering, thinning, and pruning) for getting a representation or
description of the shape of objects/regions (boundaries,
skeletons convex hulls).
A)Opening
Opening consists of an erosion followed by a dilation and can
be used to eliminate all pixels in regions that are too small to
contain the structuring element. In other words, foreground
structures that are smaller than the structure element will
disappear. In figure 3 shows opening image.
B)Reconstruction
Morphological reconstruction to extract marked objects, find
bright regions surrounded by dark pixels, detect or remove
objects touching the image border, detect or fill in object holes,
filter out spurious high or low points, and perform many other
operations.In figure 3 shows recontrcted image.
Step 3:Background Elimination(Foreground Detection)
The background elimination method is used to finding of the
motion vehicle in the traffic system.The demonstration has set
up for the proposed system in the MATLAB software.Here
the current frame is initialized in the code and elimination is
done.After elimination the background image,current image

and foreground image are show in figure 2.In that figure the
background is represented as black where as foreground
vehicle is white in color.
Step 4: Moving Vehicle Detected
Finally,moving vehicle is detected from background
environment.
VII. EXPERIMENTAL RESULT
Experimental results for moving vehicle detection using the
proposed method have been produced for many
frames.Here,we implement three different frames that represent
number of vehicles for traffic system.In figure 2 represented
as a background image for all frames,In figure 3 shows the
difference between frame 72 and its background elimination.
In figure 4 shows the difference between frame 35 and its
background elimination.
VIII. CONCLUSION
In this paper, a moving of vehicle is detected, based on BGS
method. We propose consistent BGS method which uses
thresholding to detect moving vehicle. This method is
successful in real time, and it works well for all frames from
our given .avi file.
