A Modified Feature Based Image Watermarking Scheme in NSCT Domain
In this article, we present a modified robust image watermarking scheme based on the scale-invariant feature transform (SIFT). The watermark is embedded into some local regions extracted from the original image. During embedding, the initial region is divided into some cirque sub-regions with the same area, and each watermark bit is embedded into one sub-region. Besides, it is embedded in the Non-subsampled Contourlet Transform (NSCT) domain to enhance watermark robustness. Experimental results have demonstrated the efficiency of the proposed scheme.
