摘要:A general watermarking techniques are used for copy right protection. In this watermarking scheme should achieve the features of robustness and imperceptibility. This paper represents the watermarking algorithm in the DWT domain using an Modified Haar Wavelet Transform ( MFHWT) evolutionary algorithm to satisfy both of robustness and imperceptibility. The proposed algorithm is to decompose the original image using DWT and WPT according to the size of watermark . The Modified Haar Wavelet Transform (MFHWT) is memory efficient. It is fast and simple.
