First, the 8×8 DCT blocks of the host image are rearranged into a 1-D Hilbert sequence in Hilbert scanning order, then two neighboring blocks in Hilbert sequence is pseudo-randomly selected by usin.
算法首先将原图像各8×8DCT块按Hilbert扫描顺序排列，然后每次在原图像Hilbert块索引序列中伪随机选取两个相邻8×8块，在充分考虑人类视觉系统（HVS）特性的基础上，结合块视觉因子，通过不同强度调整两相邻DCT块中对应中频系数间的大小关系，以嵌入水印信号，嵌入水印与原图像是相自适应的。
