2nd Level DWT Based On Image Watermarking
Mitesh H Patel,  Swati J Patel
As the popularity of digit media is growing, and world is becoming smaller, all due to the internet connectivity and WWW phenomena, the copyright protection of intellectual properties have become a necessity for prevention of illegal copying and content integrity verification. Discrete wavelet transforms is the most popular transformation technique adopted for image Watermarking. The insertion and extraction of the watermark in the grayscale over image is robust than the other technique like DCT and DFT. The proposed method is compared 2-level DWT based image watermarking methods by using statistical parameters such as peak-signal-to-noise-ratio (PSNR) and mean square error (MSE).
