Paper Abstract

In this paper we discuss the wavelet approach to image representation according to the action of the similarities group, i.e., according to the action of radial scaling, angular rotation and shifting. We find sufficient conditions for a discrete set of such wavelet-type functions in order to constitute a frame of L2(R2) images. Finally, an iterative algorithm to compute the desired representation coefficients is presented, and a lower bound on the rate of convergence of the algorithm is offered.
