Overview Of Video Object Tracking SystemEditor IJMTER
The goal of video object tracking system is segmenting a region of interest from a video
scene and keeping track of its motion, positioning and occlusion. There are the three steps of video
object tracking system those are object detection, object classification and object tracking. Object
detection is performed to check existence of objects in video. Then the detected object can be
classified in various categories on the basis on their shape, motion, color and texture. Object tracking
is performed using monitoring object changes. This paper we are going to take overview of different
object detection, object classification and object tracking techniques and also the comparison of
different techniques used for various stages of tracking.
Object detection is a computer technology related to computer vision and image processing that deals with detecting instances of semantic objects of a certain class (such as humans, buildings, or cars) in digital images and videos. Well-researched domains of object detection include face detection and pedestrian detection. Object detection has applications in many areas of computer vision, including image retrieval and video surveillance.

A Survey on Approaches for Object Trackingjournal ijrtem
ABSTRACT : Object detection and tracking has been a widely studied research problem in recent years. Currently system architectures are service oriented i.e. they offer number of services. All such common services are grouped together and are available as a domain called as service domain. One such service domain of our interest is LBS (location based service). The service of our interest is tracking. Tracking of moving objects is done in applications like surveillance systems, human computer interactions, object recognition, navigation systems etc. In real world, 3D, the object which we want to track is called as object of interest (OOI). Tracking has been a difficult task to apply in congested situations due to inaccurate segmentation of objects. Common problems of erroneous segmentation are long shadows, partial and full occlusion of objects with each other and with stationary items in the scene. Difficulties in tracking objects can arise due to abrupt object motion, changing appearance patterns of both the object and the scene, nonrigid object structures, object-to-object and object-to-scene occlusions, and camera motion. In this paper we analyze different approaches for moving object tracking and detection. Keywords: Multiple moving object tracking, background modeling, morphology, target localization and representation, visual surveillance.

A Critical Survey on Detection of Object and Tracking of Object With differen...Editor IJMTER
Basically object detection and object tracking are two important and challenging aspects in
many computer vision applications like surveillance system, vehicle navigation, autonomous robot
navigation, compression of video etc. Object detection is first low level important task for any video
surveillance application. To detection of moving object is a challenging task. Tracking is required in
higher level applications that required the location and shape of object. There are three key steps in
video analysis: detection of interesting moving objects, tracking of such objects from frame to frame,
and analysis of object tracks to recognize their behavior. Object detection and tracking especially for
human and vehicle is currently most active research topic. A lot of research has been undergoing
ranging from applications to noble algorithms. The main objective of this paper is to review (survey)
of various moving object detection and object tracking methodologies.

A survey on moving object tracking in videoijitjournal
The ongoing research on object tracking in video sequences has attracted many researchers. Detecting
the objects in the video and tracking its motion to identify its characteristics has been emerging as a
demanding research area in the domain of image processing and computer vision. This paper proposes a
literature review on the state of the art tracking methods, categorize them into different categories, and
then identify useful tracking methods. Most of the methods include object segmentation using background
subtraction. The tracking strategies use different methodologies like Mean-shift, Kalman filter, Particle
filter etc. The performance of the tracking methods vary with respect to background information. In this
survey, we have discussed the feature descriptors that are used in tracking to describe the appearance of
objects which are being tracked as well as object detection techniques. In this survey, we have classified
the tracking methods into three groups, and a providing a detailed description of representative methods in
each group, and find out their positive and negative aspects.
Development of Human Tracking System For Video Surveillancecscpconf
Visual surveillance in dynamic scenes, especially for human and some objects is one of the
most active research areas. An attempt has been made to this issue in this work. It has wide
spectrum of promising application including human identification to detect the suspicious
behavior, crowd flux statistics, and congestion analysis using multiple cameras.
In this paper deals with the problem of detecting and tracking multiple moving people in a static
background. Detection of foreground object is done by background subtraction. Detected
objects are identified and analyzed through different blobs. Then tracking is performed by
matching corresponding features of blob. An algorithm has been developed in this perspective
using Angular Deviation of Center of Gravity (ADCG), which gives a satisfying result for segmentation of human object.
Object Capturing In A Cluttered Scene By Using Point Feature MatchingIJERA Editor
Capturing means getting or catching. This project contains an algorithm for capturing a specific target based on the points which corresponds between reference and target image. It can capture the objects in-plane rotation and also effective to small amount of out-of plane rotation also. This method of object capturing works best for objects that exhibit in a cluttered texture patterns, which give rise to unique point feature matches. When a part of object is occluded by other objects in the scene, only features of that part are missed. As long as there are enough features detected in the unoccluded part, the object can captured. The local representation is based on the appearance. There is no need to extract geometric primitives (e.g. lines) which are generally hard to detect reliably.
Object extraction using edge, motion and saliency information from videoseSAT Journals
Abstract Object detection is a process of finding the instances of object of a certain class which is useful in analysis of video or image. There are number of algorithms have been developed so far for object detection. Object detection has got significant role in variety of areas of computer vision like video surveillance, image retrieval`. In this paper presented an efficient algorithm for moving object extraction using edge, motion and saliency information from videos. Out methodology includes 4 stages: Frame generation, Pre-processing, Foreground generation and integration of cues. Foreground generation includes edge detection using sobel edge detection algorithm, motion detection using pixel-based absolute difference algorithm and motion saliency detection. Conditional Random Field (CRF) is applied for integration of cues and thus we get better spatial information of segmented object. Keywords: Object detection, Saliency information, Sobel edge detection, CRF.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

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.

Conclusion
4. To track an object over a sequence of
images.
A method of following an object through
successive image frames to determine its
relative movement with respect to other
objects.
8. In a tracking scenario, an object can be defined as
anything that is of interest for further analysis. Objects
can be represented by their shapes. Object shape
representations commonly employed for tracking are:
Points: The object is represented by a point, that is,
centroid or set of points. Point representation is suitable
for tracking objects that occupy small regions in an image.
Primitive geometric shapes: Object shape is
represented by a rectangle, ellipse etc. these are suitable
for representing simple rigid objects and non rigid objects.
9.
10. Object silhouette and contour: contour
representation defines the boundary of an object.
The region inside the contour is called the
silhouette of the object. These are suitable for
tracking complex non rigid shapes.
Articulated shape models: These objects are
composed of body parts that are held together
with joints.
Skeletal models: object skeleton can be
extracted by applying medial axis transform to the
object silhouette. This can be used to model both
articulated and rigid objects.
11. visual input is usually achieved through digitized images
obtained from a camera connected to a digital computer.
This camera can be either stationary or moving depending
on the application.
Beyond image acquisition, the computer performs the
necessary tracking and any higher level tasks using
tracking result.
12. Every tracking method requires an object detection
mechanism either in every frame or when the object
first appears in the video.
Challenges of moving object detection:
• Loss of information caused by the 3D world on a 2D
image
• Noise in images
• Complex object motion
• Non-rigid or articulated nature of objects
• Partial or full object occlusions
• Complex object shapes
• Scene illumination changes
13.
14. Point Tracking: Objects detected in consecutive
frames are represented by points, and the association of
the points is based on the previous object state which
can include object position and motion. This approach
requires an external mechanism to detect the objects in
every frame.
Kernel Tracking: Kernel refers to the object shape and
appearance
Silhouette Tracking: Tracking is performed by
estimating the object region in each frame. Silhouette
tracking methods use the information encoded inside
the object region.

17. Segmentation is the process of identifying components
of the image. Segmentation involves operations such as
boundary detection, connected component labeling,
thresholding etc. Boundary detection finds out edges in
the image. Thresholding is the process of reducing the
grey levels in the image
18. As the name suggests this is the process of separating
the foreground and background of the image. Here it is
assumed that foreground contains the objects of interest
19. Background extraction
Once foreground is extracted a simple subtraction
operation can be used to extract the background.
Following figure illustrates this operation:
20. Camera model is an important aspect of any object-tracking
algorithm. All the existing objects tracking systems use a
preset camera model. In words camera model is directly
derived from the domain knowledge. Some of the common
camera models are –
1. Single fixed camera
Example: Road traffic tracking system
2. Multiple fixed cameras
Example: Simple surveillance system
3. Single moving camera
Example: Animation and video compression systems
4. Multiple moving cameras
Example: Robot navigation system
