Abstract
In this paper, a novel watermark method based on Periodic Haar Piecewise-Linear (PHL) transform is proposed. This solution provides high embedding capacity with negligible degradation of image quality. The PHL transform is based on integration and differentiation of periodic Haar functions. Its major advantage is the fact that it is notably fast and easy to implement and beyond that it provides good reconstruction quality. The procedure for constructing two-dimensional PHL functions and transform is introduced. Furthermore, the analysis of embedding capacity and imperceptibility of the proposed algorithm is performed. PSNR (Peak Signal to Noise Ratio) is taken as a measure of perceptual quality. The method is compared with DCT approach in certain aspects of watermarking algorithms.
