Color image watermarking scheme based on qr factorization and dwt with compatibility analysis on different wavelet filters

Since last few decades, to address the issues of digital image authenticity and integrity, various different watermarking schemes has been developed. In the current scenario of watermarking various wavelet transformations are introduced and used to develop the image watermarking schemes. In this paper, we present a compatibility analysis of the OR matrix factorization with different wavelet filters for color images. The image watermarking scheme is based on Discrete Wavelet Transformations and QR factorization method. Initially apply the DWT on the image and embedded the QR factorized watermark in the LL band of the image and different wavelet filters are applied at the time of watermark insertion and extraction. Comparative study has been also performed to judge the suitability of the scheme, in terms of robustness and quality, on different wavelets for watermarking of color images with matrix factorization. The results are tested in term of extracted watermark quality and watermarked image quality.
