Based on multi-resolution decomposition of the image watermark embedding methods Abstract: Based on Wavelet Multi-resolution analysis of the characteristics of a wavelet-based watermark embedding method, that is, before the embedded watermark scrambling to do deal with, and then after the wavelet transform in accordance with a resolution on the different characteristics of the original image and watermark wavelet decomposition, and then the same resolution level of digital watermark embedding were the same as its corresponding original image resolution level so that the watermark can not be perceived. The experimental results show that the use of the method to maintain a good image quality, and commonly used image processing method has a certain degree of robustness, is an effective method of watermark embedding.
