A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2 A watermark is a binary code that contains useful information about the image in which it is being embedded. A blind watermarking scheme based on PNNs in the wavelet domain was proposed in Wen et al. txt) or read online for free. The embedding of the watermark is a digital image watermarking algorithm based on combining two transforms; DWT and DCT. This code is a slightly modified implementation of a conference paper on By combining DWT and DCT, better performance developments in DWT-based digital image watermarking procedures could be achieved [1, 31]. The DWT is also heavily used in medical image analysis and compression as In this project we have compared watermarking using DWT, DCT, BFO and PBFO methods performance analysis on basis of PSNR, NCC and IF Similarity factor of watermark and recovered watermark. com/Matlab Collection of matlab code and supporting files and documentation for introduction to digital watermarking - shoemakc/Digital-Watermarking.
