Paper Abstract

Recently many new methods of image representation have been proposed, including wavelets, cosine packets, brushlets, edgelets, and ridgelets. Typically each of these is good for a specific class of features, but not good for others. We propose method of combining two image representations based on 2D wavelet transform and edgelet transform. The 2D wavelet transform is good at capturing point singularities, while the newly proposed edgelet transform is good at capturing linear singularities (edges). Both transforms have fast algorithms for digital images.
