Color Digital Image Watermarking Algorithm Against Geometric Attacks

摘要：

　　In order to improve watermark against geometric attacks, this paper proposed a color digital imagewatermarking embedding algorithm based on SIFT feature：first,we use the SIFT feature points to construct theDelaunay triangular mask, and its against geometric attacks based on the SIFT points’ ability to resist gemetricattacks.then, the embedding process is completed in DWT domain.Simulation experiment shows that thealgorithm has good robustness and invisibility.
