A Survey on Object Tracking and Occlusion Handling

Object tracking is one of the most important research areas in computer vision. It has wide range of applications like security and surveillance, video conferencing, motion classification & recognition, human computer interaction, animation etc. There are many challenges in this area which include change in appearance, rapid object motion and change in illumination, occlusion and clutter. Visual tracking in multiple objects results in occlusion due to object interactions that may last for quite long time periods.  So in this paper, we studied the different algorithms, methods and models which are used for object tracking and occlusion.
