A novel chaos and HVS based image watermarking algorithm

A digital image watermark algorithm based on Human Visual System (HVS) and chaotic system is presented. The positions and grey values of the watermark image pixels are shuffled by Arnold Cat Map in the spatial domain first. Then the shuffled image is encrypted by Chen's chaotic system continuou...
