Matlab Project with Source Code Image Watermarking Based On DWT and DCT

ABSTRACT

          The authenticity & copyright protection are two major problems in handling digital multimedia. The Image watermarking is most popular method for copyright protection by discrete Wavelet Transform (DWT) which performs 2 Level Decomposition of original (cover) image and watermark image is embedded in Lowest Level (LL) sub band of cover image. Inverse Discrete Wavelet Transform (IDWT) is used to recover original image from watermarked image and Discrete Cosine Transform (DCT) which convert image into Blocks of M bits and then reconstruct using IDCT. 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.
