摘要

本文采用一种任意形状的整型或非整型小波变换

结合高效的SPIHT(Set Partitioning In Hierarchical Trees)图像编码算法

分别实现了任意形状感兴趣区的无损压缩和非感兴趣的有损压缩算法.另外本文还提出了两种感兴趣区优先编码策略

可以保证在极低的码率下感兴趣区的重建质量远远好于非感兴趣区的重建质量

满足用户快速、个性化的浏览需求.这些方法得到的压缩码流都具有嵌入的特点

支持渐进传输.

Abstract

In this paper

combined with highly efficient SPIHT algorithm

an arbitrary shape integer or non-integer wavelet transform is employed to implement the lossless compression of region of interest (ROI) with arbitrary shape and lossy compression of non-ROI.Further

two strategies of ROI coding with priority are proposed to guarantee that the reconstructed image of ROI can achieve more better visual quality that non-ROI even at very low bit rate

which will satisfy the quick and individual browse requirement of users.The compressed bitstreams are all embedded and suitable for progressive transform.
