Paper Abstract

The paper presents a new approach to enhancing angiograms using M-band wavelet representations. By exploiting directional properties among M-band wavelet coefficients, M- channel directional filters are introduced in the wavelet domain to achieve edge-preserved denosing. Angiograms are then reconstructed from the transform coefficients modified by local enhancement operator based on multiscale edges. The method has lower computational complexity, yet it is capable of giving visually distinct images and offering considerable benefits in medical diagnosis.
