提出了基于四叉树分形编码的水印算法，通过在不同寻找区域中搜索最佳匹配定义域块来嵌入水印。
This paper proposes a watermarking algorithm based on quadtree fractal coding, which is to search for the optimized matched domain blocks in different regions and to embed the watermarking.
本文提出一种用于区域表达的数据结构——数字搜索树(DST)及其线性化编码(LDST)。
In this paper, we put forward a region representation data structure-digital search tree (DST) and its lineal encoding (LDST).
对原始图像进行四叉树分形编码后，通过给定子块在不同的寻找区域中搜索其最佳匹配父块来嵌入水印。
After the original image is maked to quadtree fractal coding, we embed watermarking into it by range blocks searching its most-matched domain blocks in different search regions.
