- Description: Abstract: CCTV systems are frequently monitored manually by a human observer. This human observer is typically responsible for dealing with tens or hundreds of cameras at a time. Potential security threats may easily be missed by the system’s human operators due to fatigue or being overwhelmed by the amount of change in the images...

Mean shift object tracking with occlusion handling
- De Villiers, B.Z., Clarke, W.A., Robinson, P.E.
- Authors: De Villiers, B.Z. , Clarke, W.A. , Robinson, P.E.
- Date: 2012
- Subjects: Object tracking , Target objects
- Type: Article
- Identifier: uj:6283 , ISBN 978-0-620-54601-0 , http://hdl.handle.net/10210/9889
- Description: An object tracking algorithm using the Mean Shift framework is presented which is largely invariant to both partial and full occlusions, complex backgrounds and change in scale. Multiple features are used to gain a descriptive representation of the target object. Image moments are used to determine the scale of the target object. A kalman filter is used to successfully track the target object through partial and full occlusions, the Bhattacharyya coefficient is used to determine the measurement noise estimation.

This is done by identifying feature points using the Harris corner detector, finding descriptors for the feature points and then tracking the feature points. The information gained from tracking the feature points is then used to determine the stationery probability of these features. This method is shown to successfully identify probable stationery and moving regions in video sequences.
