Non-decimated Wavelet Transform for a Shift-invariant Analysis
(Sociedade Brasileira de Matemática Aplicada e Computacional, 2018)
Due to the ability of time-frequency location, the wavelet transform has been applied in several areas of research involving signal analysis and processing, often replacing the conventional Fourier transform. The discrete ...
Mathematical tests about the existence and applications of PPS-wavelets in function approximation problems

Microcalcification enhancement and classification on mammograms using the wavelet transform
(2008-11-24)
This paper presents a method to enhance microcalcifications and classify their borders by applying the wavelet transform. Decomposing an image and removing its low frequency sub-band the microcalcifications are enhanced. ...
Partial discharge location in power transformer windings using the wavelet Laplace function
(Elsevier Science Sa, 2014-06)
Insulation system conditions in power transformers can be evaluated by means of partial discharge (PD) analyses. In fact, PD analysis is used to detect premature damage in transformer insulation system to avoid catastrophic ...
