Abstract An adaptive blind image watermarking scheme in DCT domain is proposed based on support vector machine (SVM) and genetic algorithm (GA). The original image is divided into small image blocks, and then SVM is used to classify image blocks into several classes based on their local characteristics. The embedding strength of each block is adaptively determined according to the types of the image block, and GA is used to seek optimal embedding positions. Experimental results demonstrate that the proposed scheme has good invisibility and strong robustness against several attacks.
