The Rational Dilation Wavelet Transform: A Flexible Tool for Perception-inspired Signal and Image Processing

Authors:
Vittoria Bruni
Domenico Vitulano

Keywords: contrast sensitiviy; rational dilation wavelet transform; MEL cepstrum; adaptive scale selection

Abstract:
The aim of this work is to investigate the properties of an adaptive multiscale transform for defining perception-based methods for signal and image processing. Particular attention is devoted to the possibility of partitioning the frequency plane in a flexible way, which depends on both human perception and task purpose. Examples concerning image enhancement and timbre recognition will be presented and discussed.
