Segmentation of image sequences for object oriented coding

This paper presents an algorithm for segmentation of image sequences where especially aspects for object oriented coding are taken into account. A fundamental requirement of such applications is the temporal stability of the seg-mentation. This is improved in this article compared to other existing approaches by including motion estimation into the segmentation process. Additionally a hierarchical approach enables an eecient predictive coding on one hand and a semantic data access on the other hand. As a direct result from using full colour information for the segmenta-tion process, coding of the chrominance information can be done with extremely high compression ratios. Thus there is nearly no extra coding eeort for colour images compared to greyscale images.
