The paper presents an imperceptible and robust digital watermarking algorithm using wavelet-based contourlet transform (WBCT), The WBCT can give the anisotropy optimal representation of the edges and contours in the image by virtue of the characteristics of multi-scale framework and multi-directionality. The proposed algorithm takes advantage of the significant texture information of the image to find the embedding watermarking position. Experimental results show the validity of the proposeddoi:10.1016/j.proeng.2012.01.173 fatcat:jmdh6o4d25dl5dpawk5bzxqdni
