چکیده
The Kalman filter has been used successfully in different prediction applications or state determination of a system. One of the more important fields in computer vision is the object tracking. Different movement conditions and occlusions can hinder the vision tracking of an object. In this report we present the use of the Kalman filter as a predictor in vision tracking. We consider the capacity of the Kalman filter to allow small occlusions and also the use of the extended Kalman filter to model complex movements of objects.

Robot Motion Vision Pait I: Theory
A direct method called fixation is introduced for solving the general motion vision problem, arbitrary motion relative to an arbitrary environment. This method results in a linear constraint equation which explicitly expresses the rotational velocity in terms of the translational velocity. The combination of this constraint equation with the Brightness-Change Constraint Equation solves the gene...
متن کاملHead Tracking Using Stereo
A different perspective to head tracking, one of the more studied topics in computer vision is presented here. The heavy reliance of contemporary head trackers on intensity images is countered here. The algorithm presented here, uses stereo data to track the head of a moving subject. This is used to achieve effective and accurate foreground segmentation. The head is modeled as an ellipse and tr...
متن کاملReal Time Implementation of Object Tracking through Webcam
Real time object detection and tracking is an important task in various computer vision applications. For robust object tracking the factors like object shape variation, partial and full occlusion, scene illumination variation will create significant problems. We introduce object detection and tracking approach that combines Prewitt edge detection and kalman filter. The target object’s represen...
متن کاملA Survey on Visual Object Tracking Algorithms
Due to the increasing demand of a faster and more reliable target tracking ability specifically for some critical applications such as military navigation and Robotics, using prediction and estimation concepts have been comprehensively studied. As a result of this demand, old and modern estimation algorithms based on probabilistic Baysian algorithms have been employed. In the case of visual obj...
