Research Abstract

We have carried out research and development for adaptive video coding system using matching pursuits. The following results were obtained :
1) We proposed a fast atom searching algorithm using multi-step search in non-low signal energy regions.
2) We proposed matching pursuits using a dynamic learning dictionary for video coding.
3) We proposed a region-merging method for moving object extraction based on robust motion estimation.
4) We proposed a technique that extracts shapes of moving objects by combining active contour model and watershed algorithm.
5) We proposed a moving object extraction by level set method using an adaptive speed function.
