英文摘要	Progressive coding technology based on ROI can effectively improve network transmission efficiency of remote image and meet application demand for users to concern important region with a priority. This article firstly analyzes traditional ROI coding method based on bit plane shift, points out existent deficiency of such methods; then put forward a novel ROI progressive coding algorithm. Basic principle of this algorithm is that, on the basis of regular wavelet subband, separate high frequency subbands into high frequency ROI subband and high frequency BG subband and rearrange transformed wavelet subbands, then realize progressive coding from low frequency subband, high frequency ROI subband to high frequency BG subband; at last, effectiveness and superiority of this algorithm are verified by experimental analysis. ? 2009 IEEE.; EI; 0
