| Abstract: | ROI coding can not only provide a good solution to bandwidth bottleneck and storage space limitation in communication,but also meet high-quality reconstruction for Region of Interest at low-bit-rate coding,with the combination of image compression algorithm.A new algorithm based on SPIHT is proposed for ROI coding,which can adjust the quality between region of interest and background,without coding for ROI shape.Compared with other ROI coding algorithms,the proposed algorithm has better performance in both ... |
