| Abstract: | A double image watermarking algorithm was presented on the basis of brief analysis of the common DCT transformation watermarking methods,where a unilateral watermarking in the low-frequency range and a blind-watermarking,which is based on the HVS analysis in middle-frequency range were inserted.The experiment results showed that the method designed could satisfy the request of impersonal quality and was rather convenient in use. |
