摘　　要：在交互式选取图像的感兴趣区域(ROI)的基础上,结合JPEG2000中感兴趣编码的一般位移法和分层树集合分割排序(SPIHT)算法的特性,将小波域中的低频和高频系数进行上移位处理,提出了一种新的ROI编码方法.实验结果表明:提升低频所有系数和高频中属于感兴趣区域的系数比提升所有子带中属于感兴趣系数的效果好.On the basis of interactive selected ROI,a new ROI coding algorithm is proposed by upscaling the lowfrequency and high-frequency wavelet coefficients,combining with the general scaling of JPEG2000 and the Set Partitioning in Hierarch Tree algorithm. Experimental results show that it＇s better to upgrade low-frequency coefficients and interested coefficients of high-frequency than to upgrade only interested coefficients of all subbands.
