A novel watermarking scheme based on support vector machine(SVM) in discrete wavelet transform(DWT) domain is proposed.By applying the DWT on blue channel of the color image,and the computation of the JND value in the DWT domain according to the human visual system(HVS) model,the watermark is embedded into the lower frequency subband at its adaptive strength.By the training of the SVM,it can memorize the relationship between the pixel at the embedding position and its’ neighbors when the image is undergone some attacks.Since the SVM have good learning and generalization ability,the proposed method can achieve good robust-ness.Experimental results show good robustness of proposed method against different attacks.
