Also the computation complexity is rather low . thirdly , we proposed two algorithms for 3d mesh models compression using vector quantization : one scheme is based on an extended codebook , with which the correlations between indices of adjacent vertices are adopted and
基于目前大多数可逆水印算法针对原始域媒体的不足,结合矢量量化的思想,提出了一种压缩域三维网格可逆数字水印算法:该算法通过改变矢量量化压缩过程的矢量预测方式来嵌入水印信息,使水印对于信道噪声引起的
