Compasion of Watermark Performance Using Contourlet and NSCT

摘要

Watermark performance between contourlet tranform and non-subsampled contourlet transform (NSCT) is compared by a conventional watermark scheme in this paper, which is rarely mentioned in existing literatures. Through the contrast of the transparency and robustness of the watermark, a conclusion can be drawn that NSCT is more suitable for watermark application than contourlet tranform.
