A Blind Digital Watermarking Algorithm of Colored Images Based on Integer Wavelet Transform
Lai Xiao-fang · Computer Knowledge and Technology · 2008
Due to the fact about blind withdraw of colored images, this paper propose a blind digital watermarking algorithm based on integer wavelet transform, which embeds the pretreated watermarks in the intermediate frequency of integer wavelet transform. This algorithm achieves blind withdraw watermarks, has a good hiding effect and is robust for attacks such as JPEG compression, median filter, SS attack.
