Paper Abstract

In this paper, a novel image compression scheme is presented, which is specially suited for image transmission over a narrow-band network typically required for telemedicine to remote regions. A wavelet compression algorithm is enhanced with the feature of dynamically compressing different regions of the image. This feature is provided while keeping the algorithm's embedding ability, which leads to an 'importance' embedding rather than the traditional 'energy' based embedding. To incorporate regions in a wavelet-based compression algorithm the region edges were carefully tuned to eliminate the negative influence that the wavelet transform has on the region algorithm. Test of this new algorithm on standard test images and ultrasound images showed that both the dynamic and region-based features could be incorporated into the wavelet algorithm with only a small overhead.
