| 摘 要： | JPEG2000采用感兴趣区域编码能够实现一幅图像的多种质量压缩。针对以往提供的各种方法都对一个感兴趣区域进行编码的缺点，提出了实现多个感兴趣区域的无损压缩的方法。其主要特点是利用优先级的方法重新排列编码数据流中的包，通过优先级排列可以区分ROI和背景区域在每个分解级中的相对重要性，而且在同一幅图像中有多个感兴趣区域的时候，它能够提供多个优先级，能够很好的实现多个感兴趣区域无损压缩的图像编码。

| Abstract: | JPEG2000 realized multiple quality compression in an image through Region Of interest(ROI) coding.Concerning about the disadvantage of formerly provided each method all aimed at coding a Region Of interest,a new approach was proposed to realize multiple ROIs coding.Its characteristic is that it adopt the priority method to rearrange the packets of coding data.By the rearrangement of priority can specify the relative importance of the background and ROIs data in each decomposition level.Moreover,when there are multiple region of interest in the same image,a region can have its own priority level,it can realize image coding with multiple region of interest lossless compression. |
