Abstract:
This paper describes the studies on methods of
compression for medical echocardiography sequence, or called
ultrasound sequential images in this paper. The aim is to find a
combination of methods, which achieves the highest overall
compression performance. Our approach is based on region of
interest (ROI), i.e. to segment the image into several regions
according to their spatial characteristics, and then compress them
separately with different methods. In doing so, we are able to
achieve a relatively high compression ratio of about 7.2 while
preserving the lossless contents of important regions.
