The image's histogram represents the statistical feature of distribution of pixels and is not related to the specific positions of pixels. This feature gives histogram-based algorithms the ability to resist geometric attacks, but the embedding capacity is limited. In this paper we combine two typical histogram-based functions and give two relationships to three bins in a group. So the embedding capacity...
The image's histogram use the statistical features of an image and is regardless of the specific distribution of image pixels. With this feature, the histogram-based image watermark algorithm can avoid the desynchronization that geometric attacks bring to image and is robust to geometric attacks. Typical histogram algorithms can resist translation and crop attacks, but the ability to resist rotation,...
