There are several different approaches for moving object extraction, clustering is one of object extraction method with a stronger teorical foundation used in many applications. And need high performance in many extraction process of moving object. We compare K-Means and Self-Organizing Map method for extraction moving objects, for performance measurement of moving object extraction by applying MSE and PSNR. According to experimental result that the MSE value of K-Means is smaller than Self-Organizing Map. It is also that PSNR of K-Means is higher than Self-Organizing Map algorithm. The result proves that K-Means is a promising method to cluster pixels in moving objects extraction.
HUMAN MOTION DETECTION AND TRACKING FOR VIDEO SURVEILLANCEAswinraj Manickam
An approach to detect and track groups of people in video-surveillance applications, and to automatically recognize their behavior.
This method keeps track of individuals moving together by maintaining a spacial and temporal group coherence.
First, people are individually detected and tracked. Second, their trajectories are analyzed over a temporal window and clustered using the Mean-Shift algorithm.
A coherence value describes how well a set of people can be described as a group. Furthermore, we propose a formal event description language.
The group events recognition approach is successfully validated on 4 camera views from 3 data sets: an airport, a subway, a shopping center corridor and an entrance hall.

Internet data almost double every year. The need of multimedia communication
is less storage space and fast transmission. So, the large volume of video data has become
the reason for video compression. The aim of this paper is to achieve temporal compression
for three-dimensional (3D) videos using motion estimation-compensation and wavelets.
Instead of performing a two-dimensional (2D) motion search, as is common in conventional
video codec’s, the use of a 3D motion search has been proposed, that is able to better exploit
the temporal correlations of 3D content. This leads to more accurate motion prediction and
a smaller residual. The discrete wavelet transform (DWT) compression scheme has been
added for better compression ratio. The DWT has a high-energy compaction property thus
greatly impacted the field of compression. The quality parameters peak signal to noise ratio
(PSNR) and mean square error (MSE) have been calculated. The simulation results shows
that the proposed work improves the PSNR from existing work.

Design and implementation of video tracking system based on camera field of viewsipij
The basic idea of this paper is to design and implement of video tracking system based on Camera Field of
View (CFOV), Otsu’s method was used to detect targets such as vehicles and people. Whereas most
algorithms were spent a lot of time to execute the process, an algorithm was developed to achieve it in a
little time. The histogram projection was used in both directional to detect target from search region,
which is robust to various light conditions in Charge Couple Device (CCD) camera images and saves
computation time.

Analysis and Detection of Image Forgery Methodologiesijsrd.com
"Forgery" is a subjective word. An image can become a forgery based upon the context in which it is used. An image altered for fun or someone who has taken a bad photo, but has been altered to improve its appearance cannot be considered a forgery even though it has been altered from its original capture. The other side of forgery are those who perpetuate a forgery for gain and prestige. They create an image in which to dupe the recipient into believing the image is real and from this they are able to gain payment and fame. Detecting these types of forgeries has become serious problem at present. To determine whether a digital image is original or doctored is a big challenge. To find the marks of tampering in a digital image is a challenging task. Now these marks of tampering can be done by various operations such as rotation, scaling, JPEG compression, Gaussian noise etc. called as attacks. There are various methods proposed in this field in recent years to detect above mentioned attacks. This paper provides a detailed analysis of different approaches and methodologies used to detect image forgery. It is also analysed that block-based features methods are robust to Gaussian noise and JPEG compression and the key point-based feature methods are robust to rotation and scaling.
A Novel Approach for Moving Object Detection from Dynamic BackgroundIJERA Editor
In computer vision application, moving object detection is the key technology for intelligent video monitoring
system. Performance of an automated visual surveillance system considerably depends on its ability to detect
moving objects in thermodynamic environment. A subsequent action, such as tracking, analyzing the motion or
identifying objects, requires an accurate extraction of the foreground objects, making moving object detection a
crucial part of the system. The aim of this paper is to detect real moving objects from un-stationary background
regions (such as branches and leafs of a tree or a flag waving in the wind), limiting false negatives (objects
pixels that are not detected) as much as possible. In addition, it is assumed that the models of the target objects
and their motion are unknown, so as to achieve maximum application independence (i.e. algorithm works under
the non-prior training).

This work presents a new method to enhance the performance of fireworks algorithm to generate a prime key for multiple users. A threshold technique in image segmentation is used as one of the major steps. It is used processing the digital image. Some useful algorithms and methods for dividing and sharing an image, including measuring, recognizing, and recognizing, are common. In this research, we proposed a hybrid technique of fireworks and camel herd algorithms (HFCA), where Fireworks are based on 3-dimension (3D) logistic chaotic maps. Both, the Otsu method and the convolution technique are used in the pre-processing image for further analysis. The Otsu is employed to segment the image and find the threshold for each image, and convolution is used to extract the features of the used images. The sample of the images consists of two images of fingerprints taken from the Biometric System Lab (University of Bologna). The performance of the anticipated method is evaluated by using FVC2004 dataset. The results of the work enhanced algorithm, so quick response code (QRcode) is used to generate a stream key by using random text or number, which is a class of symmetric-key algorithm that operates on individual bits or bytes.

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.

ROBUST STATISTICAL APPROACH FOR EXTRACTION OF MOVING HUMAN SILHOUETTES FROM V...ijitjournal
Human pose estimation is one of the key problems in computer visionthat has been studied in the recent
years. The significance of human pose estimation is in the higher level tasks of understanding human
actions applications such as recognition of anomalous actions present in videos and many other related
applications. The human poses can be estimated by extracting silhouettes of humans as silhouettes are
robust to variations and it gives the shape information of the human body. Some common challenges
include illumination changes, variation in environments, and variation in human appearances. Thus there
is a need for a robust method for human pose estimation. This paper presents a study and analysis of
approaches existing for silhouette extraction and proposes a robust technique for extracting human
silhouettes in video sequences. Gaussian Mixture Model (GMM) A statistical approach is combined with
HSV (Hue, Saturation and Value) color space model for a robust background model that is used for
background subtraction to produce foreground blobs, called human silhouettes. Morphological operations
are then performed on foreground blobs from background subtraction. The silhouettes obtained from this
work can be used in further tasks associated with human action interpretation and activity processes like
human action classification, human pose estimation and action recognition or action interpretation.
Effective Object Detection and Background Subtraction by using M.O.IIJMTST Journal
This paper proposes efficient motion detection and people counting based on background subtraction using dynamic threshold approach with mathematical morphology. Here these different methods are used effectively for object detection and compare these performance based on accurate detection. Here the techniques frame differences, dynamic threshold based detection will be used. After the object foreground detection, the parameters like speed, velocity motion will be determined. For this, most of previous methods depend on the assumption that the background is static over short time periods. In dynamic threshold based object detection, morphological process and filtering also used effectively for unwanted pixel removal from the background. The background frame will be updated by comparing the current frame intensities with reference frame. Along with this dynamic threshold, mathematical morphology also used which has an ability of greatly attenuating color variations generated by background motions while still highlighting moving objects. Finally the simulated results will be shown that used approximate median with mathematical morphology approach is effective rather than prior background subtraction methods in dynamic texture scenes and performance parameters of moving object such sensitivity, speed and velocity will be evaluated by using MOI.
Video surveillance systems are very important in our everyday life. Video surveillance applications are

low light conditions. Surveillance video may not be seen clearly. Especially under the weak illumination
conditions. The details of the image are very poor at night. Most of the previous work has focused on
daytime Surveillance. This paper proposes a method of Human detection in hours of darkness (night time)
using Gaussian Mixture Model (GMM) in real night environment employing an infrared radiation camera.
Infrared video is taken as Input to perform Human detection at night. Then the video was processed using
Gaussian mixture model algorithm, it was confirmed that by using this method accurate detection of human

Stereo Vision Human Motion Detection and Tracking in Uncontrolled EnvironmentTELKOMNIKA JOURNAL
Stereo vision in detecting human motion is an emerging research for automation, robotics, and sports science field due to the advancement of imaging sensors and information technology. The difficulty of human motion detection and tracking is relatively complex when it is applied to uncontrolled environment. In this paper, a hybrid filter approach is proposed to detect human motion in the stereo vision. The hybrid filter approach integrates Gaussian filter and median filter to reduce the coverage of shadow and sudden change of illumination. In addition, sequential thinning and thickening morphological method is used to construct the skeleton model. The proposed hybrid approach is compared with the normalized filter. As a result, the proposed approach produces better skeleton model with less influential effect on shadow and illumination. The output results of the proposed approach can show up to 86% of average accuracy matched with skeleton model. In addition, obtains approximately 94% of sensitivity measurement in the stereo vision. The proposed approach using hybrid filter and sequential morphology could improve the performance of the detection in the uncontrolled environment.

Integration of poses to enhance the shape of the object tracking from a singl...eSAT Journals
Abstract In computer vision, tracking human pose has received a growing attention in recent years. The existing methods used multi-view videos and camera calibrations to enhance the shape of the object in 3D view. In this paper, tracking and partial reconstruction of the shape of the object from a single view video is identified. The goal of the proposed integrated method is to detect the movement of a person more accurately in 2D view. The integrated method is a combination of Silhouette based pose estimation and Scene flow based pose estimation. The silhouette based pose estimation is used to enhance the shape of the object for 3D reconstruction and scene flow based pose estimation is used to capture the size as well as the stability of the object. By integrating these two poses, the accurate shape of the object has been calculated from a single view video. Keywords: Pose Estimation, optical Flow, Silhouette, Object Reconstruction, 3D Objects

A Robust Method for Moving Object Detection Using Modified Statistical Mean M...ijait
Moving object detection is low-level, important task for any visual surveillance system. One of the aim of this paper is to, to describe various approaches of moving object detection such as background subtraction, temporal difference, as well as pros and cons of these techniques. A statistical mean technique [10] has been used to overcome the problem in previous techniques. Even statistical mean method also suffers with the problem of superfluous effects of foreground objects. In this paper, the presented method tries to overcome this effect as well as reduces the computational complexity up to some extent. In this paper, a robust algorithm for automatic, noise detection and removal from moving objects in video sequences is presented. The algorithm considers static camera parameters.
Interactive Full-Body Motion Capture Using Infrared Sensor Network ijcga
Traditional motion capture (mocap) has been well-studied in visual science for the last decades. However the field is mostly about capturing precise animation to be used in specific applications after intensive post processing such as studying biomechanics or rigging models in movies. These data sets are normally captured in complex laboratory environments with sophisticated equipment thus making motion capture a
field that is mostly exclusive to professional animators. In addition, obtrusive sensors must be attached to actors and calibrated within the capturing system, resulting in limited and unnatural motion. In recent year the rise of computer vision and interactive entertainment opened the gate for a different type of motion capture which focuses on producing optical markerless or mechanical sensorless motion capture. Furthermore a wide array of low-cost device are released that are easy to use for less mission critical applications. This paper describes a new technique of using multiple infrared devices to process data from multiple infrared sensors to enhance the flexibility and accuracy of the markerless mocap using commodity
devices such as Kinect. The method involves analyzing each individual sensor data, decompose and rebuild
them into a uniformed skeleton across all sensors. We then assign criteria to define the confidence level of
captured signal from sensor. Each sensor operates on its own process and communicates through MPI.
Our method emphasizes on the need of minimum calculation overhead for better real time performance
while being able to maintain good scalability.
This paper represents a survey of various methods of video surveillance system which improves the security. The aim of this paper is to review of various moving object detection technics.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Abstract: Detection and tracking of humans in a video has great potential applications. The paper proposes a
novel scheme for performing automated human detection and tracking in videos. The method consist of two
steps namely, motion detection and human – non human classification. Motion detection is done by performing
background subtraction. The background model is generated using a mixture of Gaussian distributions. The
human – non human classification is done by generating the feature vector from the local binary pattern of
segmented regions. A radial basis function based support vector machine is used for classification. The
proposed scheme was tested on some test videos and was able to detect and track human figures with acceptable
accuracy.
Keywords: Background modeling, background subtraction, Gaussian mixture model, human detection, human
tracking, local binary pattern, support vector machine
I. Introduction
Object tracking is the process of tracing the location of an object of interest. The main application of
object tracking comes in the field of automatic video surveillance. Nowadays almost all buildings and roads are
provided with closed circuit television (CCTV) security cameras. The visuals from these CCTV cameras serve a
great deal in monitoring human activities. Thus these become very much helpful in prevention of crime, theft,
etc. The main problem associated with this is that a lot of human workforces are required for the monitoring of
these video sequences. It is in this context that the need for an automatic surveillance system arises.
The conventionally used technique for motion detection in video sequences is to perform background
subtraction [5] technique. The background subtraction technique subtracts a background mask from each of the
video sequences and detects if there is any change in it. The simplest background mask is the image of the scene
without any moving object in it. Another method is to choose the background mask as an average of first N
number of frames of the video[8]. But these background masks will simply fail if there is any illumination
change in the scene of interest. So as a solution to this problem, the background mask will be modeled [1]. For
this, several techniques such as statistical modeling, fuzzy background modeling [6], neural network
background modeling [7], background clustering[1], etc are present. Once the background is modeled and the
foreground is computed by subtracting the background mask from the video frame, the next step is to determine
whether the foreground contains any object of interest. For this an object recognition technique has to be used.
In the human detection and tracking system, the object of interest is humans. Several techniques have been
proposed for detecting a human figure in an image such as histogram of oriented gradients [9], partial least
squares analysis [10], Haar-cascade classifier[11], etc.
The proposed method combines an adaptive statistical background modeling[2] technique and a local
binary pattern[3] feature for the detection and locating of a human being in a video scene. Since an adaptive
statistical background modeling technique is used to model the background mask, the proposed scheme is very
much resistant to illumination changes. Also the moving objects in the scene are further classified as human or
non human using the local binary pattern feature descriptor. The proposed scheme is also resilient to changes
occurring in the background scene over time and thus it can successfully detect and track moving human figures
in a video. The block diagram of the proposed scheme is given in Fig. 1
II. Background Subtraction for Motion Detection
The proposed method uses a background subtraction technique for locating the moving objects in the
scene. Background subtraction uses a model of the background to find the foreground objects present in the
video frame. The simplest technique uses a static background image as the background model. These models
fail when the scene under consideration is of varying illumination. In order to cope with this problem, the
proposed method uses a statistical background model as the background mask. The model is constructed from a
mixture of Gaussian distributions. The method was originally proposed by Grimson and Stauffer[12] and later
modified by KaewTraKulPong and Bowden[2].

In this method, each pixel in the background is modelled by a mixture of a small number of Gaussian
distributions. Generally, the number of Gaussian mixtures used ranges from 3 to 5. Each Gaussian distribution is
used to model a single colour space. Consider the RGB colour space. The colour space consists of three colours
namely, red, green and blue. Let the number of Gaussian distributions be „K‟. Now, each pixel „X‟ in the frame
will be modelled using these „K‟ Gaussian distributions. At any time instant „N‟, the probability that the pixel at
a particular location has the value „XN‟ is given by

Where, the threshold T is the minimum amount of background present in the entire scene. If the pixel
value does not match any of the distribution, the pixel will be marked as a foreground pixel.
III. Human Detection System
After performing the background subtraction technique mentioned above, the foreground containing
the moving objects are segmented. The next step is to determine whether the foreground object is human or not.
This is required because the foreground may contain other moving objects such as vehicles, animals, or
other moving objects such as leaves, trees, etc. The local binary pattern of the moving object is used for
classifying the object as human or not. The classification is done using a support vector machine.
Local binary pattern (LBP) was introduced in 1996 by Ojala et al[3]. It was first used for face
recognition applications. Later, several papers were published that used LBP in applications such as image
retrieval, texture analysis, motion analysis, etc. In this paper, the LBP is used for detecting whether the object
under consideration is human or not. Fig. 2 explains how the LBP of an image is generated. A local binary
pattern corresponding to each of the pixel values present in the image will be generated and the original pixel
value will be replaced with this number. The resulting image is called local binary pattern image. Consider Fig.
2. The pixel under consideration is the pixel at location (2,2) with value 200 In order to find the LBP of this
pixel, the immediate neighbours of this pixel will be thresholded with 200 as the threshold value. This results in
eight binary values around the pixel at (2,2) These binary values will be then converted to decimal form and the
pixel at (2,2) will be replaced with this value. In this way the LBP of all the pixels will be calculated to obtain
the LBP image. A modification to the LBP mentioned above is the uniform local binary pattern (ULBP). A
binary sequence is said to be a uniform pattern if the number of transitions present in the pattern is exactly two
3. Human Detection and Tracking System for Automatic Video Surveillance
www.ijeijournal.com Page | 60
in number. Transitions can be a change from 0 to 1 or from 1 to 0. For example, the sequence 10001000 is not a
uniform pattern since it contains four transitions. The sequence 00011100 is a uniform pattern since the number
of transitions is only two. Consider the UBLP computation of an image. Suppose that the LBP of a pixel was
found to be non-uniform. Then, the pixel value will not be replaced with the LBP value. Instead, the original
pixel value will be retained. On the other hand, if the LBP was uniform, then the pixel value will be replaced
with the LBP. The proposed scheme for human detection uses uniform local binary patterns for feature
extraction and classification. Fig. 3 and Fig. 4 show the local binary pattern images of pedestrian image and car
image respectively.
Figure 2: Local binary pattern computation
Once the ULBP of an image is computed, the next step is to extract the feature vector from the ULBP
image. The feature is extracted as follows. First, the image will be divided into small blocks of size mxn. Then
the histogram of each block will be calculated and concatenated together to obtain the feature vector. The
similarity between these feature vectors are used for comparing images. The usage of uniform local binary
pattern provides two major advantages. Firstly, for a „p‟ bit binary sequence, the number of sequences with two
transitions are given by p(p-1). Therefore, for a 8 bit sequence, the number of uniform sequences is given by 56.
This reduces the length of the histogram to a great extend. Secondly, the uniform local binary pattern
detects only the important features such as line ends, edges, corners, etc.
IV. Experiments and Results
Two different experiments were conducted to determine the efficiency of the proposed scheme. The
first experiment was done to check whether the local binary pattern is able to successfully classify human
figures from other objects. The radial basis function SVM was used for the classification. The MIT CBCL
pedestrian database #1 was used as the human training set and random images obtained from the internet was
used as non human images. The SVM was trained using 100 human images and 100 non human images. The
remaining images in the pedestrian database and other random images from the internet were used for testing the
SVM. The pedestrian image was of size 128x64. After the computation of the uniform local binary pattern
image the LBP image is divided into 8 blocks. Thus each block is of size 16x8. Then the histogram of each
block is found and concatenated together to obtain the feature vector. The non human images found from the
internet were first resized to 128x64 dimensions and then the features were found. The recognition accuracy was
found to be 96.34%. This result shows that the local binary pattern is indeed a good feature for the classification
of human and non-human objects.

The second experiment was conducted to determine the efficacy of the proposed scheme as a human
detection and tracking system. The testing was done on videos taken using Sony Cyber-shot DSC-W710 at a
frame rate of 30fps. The MIT CBSL pedestrian #1 database was used for training the SVM. The background
model of the scene was generated using a Gaussian mixture model with the following parameters: number of
Gaussian mixtures used, K=5; initial learning rate, ρ=0.005; threshold, T=0.7; variance of Gaussian distribution,
σ=900. The proposed scheme was tested on three different videos. Video1 contained only a single human. Video
2 contained multiple humans and video3 contained humans as well as vehicles. The moving objects in the video
frame were obtained after the background subtraction step. Then each of the moving objects were separated and
resized to the dimension 128x64. Then the feature vectors were extracted. Recognition accuracy was computed
by counting the correctly classified frames in the entire video. The recognition result is shown in TABLE 1.

V. Conclusion
The paper proposes a novel method for detecting and tracking humans in a video. The proposed
scheme consists of a background subtraction technique for locating the moving objects within a scene and a
local binary pattern based feature for classifying the moving objects as human or not. The background of the
scene was modelled using a Gaussian mixture model and was used for performing background subtraction. The
local binary pattern of the moving objects was used as the feature vector for human – non human classification.
The classification was done using a support vector machine (SVM). The proposed human detection and
tracking system was tested on a number of test videos. The experimental result shows that the proposed scheme
can be used for the detection and tracking of humans in CCTV camera videos for automatic surveillance.
