Video Objects Segmentation and Tracking in Video Sequences

The ISO MPEG4 has attracted much attention recently for providing a standard solution for object-based coding and multimedia data access and manipulation.So content-based representation and coding of the visual information is currently becoming an extremely active research field.Object-based video coding can provide greater compression ratio and better quality of reconstructed images.Video objects segmentation is a key technology in object-based video coding and multimedia data access etc. This paper depictes and analyzes and compares the video objects automatic segmentation and tracking processes and methods.Existing problems and development prospect in this field are described.
