JPEG2000中感兴趣区域的编码方法

感兴趣区域编码是JPEG2000图像编码标准的一个特点。在JPEG2000中定义了两种主要的感兴趣编码的方法,分别是Maxshift算法和一般位移算法。另外,很多改进的ROI编码算法被相继提出,如本文中提到的BbBshift算法,PSBshift算法,Hbshift算法。其中,Hbshift是相对较优的算法。本文将对ROI编码的几种主要算法作详细介绍和比较。

Region-Of-Interest Coding Methods in JPEG2000

Region-Of-Interest Coding is one of the new features included in JPEG2000.Two methods which are Maxshift method and the general scaling based method are defined in JPEG2000 standard. There are a few new improved methods. As mentioned in this paper, BbBshift method,PSBshift Method, and Hbshift method which is relatively most superior ROI coding method.In this paper all these methods would be introduced comprehensively.
