The algorithm performs discrete cosine transform on sub image of host image, which is cover by visible watermarking, and compresses sub image by select the set of visually important DCT coefficients. Then, the algorithm hides the compressed sub image, which is encrypted by the hash function that is constructed by Rijndael code, in the high coefficient of wavelet domain.

算法将水印图像与宿主图像进行融合，并对隐藏子图采用DCT变换，按Zig_Zag排序保留视觉重要DCT系数的方法作压缩处理，并利用Rijndael密码构造单向Hash函数作加密处理，最终分散嵌入到宿主图像的带参数的整数小波域中的高频系数，实现了可见水印的有效嵌入。

Two steganography security definitions fitted for images are proposed from different points of view. One is in terms of the relative entropy based on the reversible de-correlation transform. The other is in terms of the conditional relative entropy using the markov random field model for images.

This contour phase correlation method is superior to the conventional phase correlation in two aspects. Firstly, the contours of images are extracted, and the phase correlation is applied to the contours of images instead of the whole original images, which is more efficient and robust. Secondly, when there are multiple peak values approximate to the maximum peak value in the δ function array, the corresponding translations can be regarded as candidate translations and calculated separately, and the best translation should be determined by the optimization of conformability of two images in the overlapping area.

本轮廓相位相关算法对常规的相位相关算法作了两点改进：(1)提取出图像的轮廓，只对二值化的轮廓图像进行相位相关计算，效率和鲁棒性提高；(2)当相位相关的δ函数阵列中存在多个和最大峰值比较接近的峰值时，将其对应的平移量都作为候选平移量，然后根据重叠区图像的一致性选取其中的最佳值。
