چکیده انگلیسی

It is an important issue to deal with imperceptibility and robustness in image watermarking system. This paper proposed a new watermarking method based on HVS and framelet transform. On the basis of spatial domain HVS feature, this paper establishes a visual masking model for framelet domain. Moreover, an embedding position optimization method in the low-luminance smooth area is proposed, which tries to avoid the visual distortion in that area caused by congregate embedding. In accordance with the framelet visual masking matrix, the framelet coefficients are selected to embed watermark adaptively. Experimental results show that the proposed method delivers better performance than the previous ones.
