| Abstract: | A blind digital image watermarking algorithm based on DCT is put forward. The watermarking image is embedded in the load image through adjusting the magnitude relationship of the chosen medium frequency coefficient, which is easy. Experiments prove the strong ability of proposed algorithmin resisting shear attracts, noise attracts, compression attracts, and other common attracts. |
