Object-based fractal coding of video sequence

Summary form only given. In order to realize the efficient and economical transmission/storage of video sequences, and also the object-based functionality of MPEG-4, we propose a new video sequence compression scheme. The CPM/NCIM fractal coding scheme is applied on each object independently by a prior image segmentation map (alpha plane) which is exactly the same as defined in MPEG-4. We encode the first frames of the video sequence as a "set" using circular prediction mapping (CPM) and encode the remaining frames using noncontractive interframe mapping (NCIM). The CPM and NCIM accomplish the motion estimation/compensation which can exploit the high temporal correlations between the adjacent frames of the video sequence. The tested results with a nature video sequence provides promising performances at low bit rate coding, such as applications in video conferencing. We believe it will be a powerful and efficient technique for object-based video sequence coding.
