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 paper we have compared
watermarking using DWT & DWT-DCT methods performance analysis on basis of
PSNR, Similarity factor of watermark and recovered watermark.
