Paper Abstract

In this work, we propose new multiresolution techniques for data embedding in imagery. The wavelet extrema of the image are exploited to embed data. We use the wavelet extrema of the dyadic non-orthogonal wavelet transform. These extrema represent high frequency points in the image, hence modifications in their neighborhoods have minor visual distortion.
