By unevenly upscaling the wavelet coefficients, the method can not only reconstruct the ROI data priorly in a low bit-rate codestream, but make the progressive reconstruction of the image data more convenient for the human vision system.

• 该方法根据人类视觉生理特点，将小波变换系数进行非均匀的上移位处理，不仅能够保证感兴趣区域图像数据在低比特数据流中的优先恢复，还实现了使图像的渐进恢复过程更加适合人类生理视觉感观特点的效果。
