| Abstract: | A new method of digital watermarking for color images based on DWT and HVS is proposed in the paper. The method uses HVS model to embeds watermark in discrete wavelet transform area. And it applies the way of de-parting groups instead of simple averaging in detecting the watermark. The method makes the watermarking be bet-ter recovered when the images are attracted. |
