Abstract: Wavelet transforms, exploits the spatial and frequency information of transformed data in multiple resolutions and it is closer to the human visual system because, it splits the input image into several frequency of bands processed independently. The image watermarking and recovering of watermarked image based on various orthogonal wavelets is performed by decomposing into several bands in the form of pyramidal structure. In this method the copyright insertion, extraction and recovering of image is performed through two levels decomposition of various orthogonal wavelets. The embedding is performed by using the largest coefficients in all bands of details represent the high and middle frequencies of the image. Finally the orthogonal wavelets watermarking is experimentally evaluated using peak signal noise ratio, which shows the comparative result against robustness, quality of copyright and watermarked image before and after attacks and quality of reconstructed wat!
