Filtering of Audio Signals Using Discrete Wavelet Transforms

open access: yesMathematics, 2023
Nonlinear diffusion has been proved to be an indispensable approach for the removal of noise in image processing. In this paper, we employ nonlinear diffusion for the purpose of denoising audio signals in order to have this approach also recognized as a ...

Accelerating discrete wavelet transforms on GPUS [PDF]

open access: yes2017 IEEE International Conference on Image Processing (ICIP), 2017
The two-dimensional discrete wavelet transform has a huge number of applications in image-processing techniques. Until now, several papers compared the performance of such transform on graphics processing units (GPUs). However, all of them only dealt with lifting and convolution computation schemes.

Local transformations with a singular wavelet

open access: yesInformatika, 2020
The paper considers a local wavelet transform with a singular basis wavelet. The problem of nonparametric approximation of a function is solved by the use of the  sequence of local wavelet transforms.
