A Digital Watermarking Algorithm against Dithering Attack Based on Watson Perceptual Pattern

摘要：

In practice, we proposed a digital watermarking algorithm against dithering attack. This scheme firstly broke up an original image into 8×8 blocks and watermark was put into the image by the relation of DC coefficients in disjoint blocks. The intensity of watermarking was computed with the help of Watson perceptual pattern. Experimental results suggested that the algorithm was robust for dithering and other common image processing attacks.
