SINOPSIS

Two-dimensional wavelet transformation is studied. A method for calculation of two-dimensional indivisible wavelet-filters with optimized frequency selectivity is proposed to solve the problem of image compression/reconstruction. Examples of optimum filters, synthesized for text images, are given. An algorithm for synthesis of wavelet filters "approximating" the optimum one is proposed. Results of optimized wavelet filters and Daubechi wavelet filters for image compression are compared.
