Abstract	Dual watermark image algorithm based on image segmentation and linear weighted codec technology is proposed. In the method, the original image embedded watermark areas are obtained using traditional image segmentation techniques (block truncation code and quadtree segmentation technique). Transform the watermark areas using DWT and scramble the dual watermarks by an m-sequence transformation. After that, use SVD method in HL coefficients and embed the first watermark. The single watermark image can be got after the inverse SVD and DWT transformed. Use the linear weighted codec technology to transform domain watermark image embedded another watermark. Experiments show that the image watermarking algorithm has better robustness of image rotation, compression, noise, filtering attack.
