Research on A Complementary Image Watermarking Algorithm |
| |
| Abstract: | ： In this paper,We have given a general framework of complementary image watermarking algorithm in the frequency domain,which embes a watermark in the low－frequency and in the middle－high－frequency separately,so as to satisfy the complementary of robustness.And proposes a DWT－based complementary image watermarking algorithm and Experimental results show that this algorithm is valid. |
