Abstract

We recently proposed a new family of nonredundant directional image transforms using hybrid wavelets and directional filter banks (HWD). In this paper we develop and analyze an HWD family algorithm for blind multiplicative watermarking. We approximate the watermarked coefficients by a generalized Gaussian distribution probability model and use a locally optimal detector. Then, we compare the performance of the HWD family to that of wavelet-based image watermarking.
