摘要
An image adaptive watermark casting method based on the wavelet transform is proposed. To increase the robustness and perceptual invisibility, the algorithm is combined with the quantisation model based on the human visual system. The number of factors that affect the noise sensitivity of the human eye are taken into consideration. Experimental results demonstrate the robustness of the algorithm to high compression environments.
