A Multiresolution Watermark for Digital Images

Abstract

In this paper, we introduce a new multiresolution watermarking method for digital images. The method is based on the discrete wavelet transform (DWT). Pseudo-random codes are added to the large coe cients at the high and middle frequency bands of the DWT of an image. It is shown that this method is more robust to often proposed methods to some common image… (More)
