We propose a watermarking algorithm for digital image based on DWT and SVD by choosing a region of interest and embedding the watermark in the same. The region for choosing a region of interest is an area which contains important information and should be sent through media with out any distortions and attacks. Image quality is checked out with a number of widely used metrics such as PSNR, Normalized correlation. The work is based on this algorithm, demonstrates that the watermarking is robust to the common signal processing techniques including JPEG compressing noise, median filter, Gaussian Blur and Gaussian noise. Experimental results show that the DWT-SVD watermarking scheme is more robust than the DWT method. July - September 2009 Copyright © 2009 i-manager publications.
