分析了感兴趣区域的编码算法,对其中的最大移位法进行了改进,提出了一种基于零树结构的感兴趣区图像编码算法,给出了具体算法和实验结果,并与一般EZW压缩算法进行了比较。实验结果表明这种算法既保证了感兴趣区域的图像质量,又有较高的压缩比。
The algorithm of coding region of interest is analyzed and the maximum shift method is improved. An image coding algorithm of region of interest based on zerotree structure is proposed. The algorithm and experimental results are given. Compared with the general EZW compression Algorithms are compared. Experimental results show that this algorithm not only ensures the image quality of the region of interest, but also has a higher compression ratio.
