Abstract
This paper addresses a new robust watermarking scheme based on Nonsubsampled Contourlet Transform (NSCT) for digital images. The watermark is embedded in the selected important sub-blocks in the low frequency sub-band in the nonsubsampled contourlet domain using the tree structure and the texture feature of the NSCT coefficients. Experimental results show that this algorithm gives better robustness and invisibility.
