A tree of median pyramidal decompositions with an application to signal denoising
TL;DR: Numerical simulations have shown that the proposed algorithm is more effective for signal denoising than the method based on the traditional median pyramidal transform.
Proceedings ArticleDOI
Wavelet packets and genetic algorithms
TL;DR: The result is an extension of Bethke's (1980) work who discovered an efficient method for calculating schema average fitness values using the Walsh transform.
Proceedings ArticleDOI
Effective detection and elimination of impulsive noise with a minimal image smoothing
TL;DR: Two solutions to the edge preservation problem of impulsive noise filtering are presented, one of which is based on an impulse detector and the other based on threshold Boolean filtering, when the binary slices of an image, obtained by the threshold decomposition, are processed by original Boolean functions.

Statistical evaluation of visual quality metrics for image denoising
TL;DR: The new test image database, FLT, containing 75 noise-free ‘reference’ images and 300 filtered (‘distorted’) images is developed, and can be effectively used to design new image visual quality metrics for image denoising.

On fast hadamard transforms of Williamson type
TL;DR: This paper develops fast Hadamard transforms based on special classes of hadamard matrices, namely, the Williamson type HadamARD matrices.
