Dual-tree complex wavelet transform applied to fault monitoring and identification in aeronautical structures
(2014-01-01)
This paper proposes the application of the dual-tree complex wavelet transform on fault monitoring and identification in aeronautical structures. For this purpose, a multiscale analysis from phase of the complex wavelet ...
Plasma structure extraction from lasco images by the dual-tree complex wavelet transform
(2015-01-01)
Images of the Sun obtained in distinct electromagnetic ranges can be very useful to investigate electrodynamical processes that occur in this star. This work analyzes the application of a two-dimensional version of the ...
An immunological approach based on the negative selection algorithm for real noise classification in speech signals
(2017-02-01)
This paper presents a new approach to detect and classify background noise in speech sentences based on the negative selection algorithm and dual-tree complex wavelet transform. The energy of the complex wavelet coefficients ...
Wavelet shrinkage using adaptive structured sparsity constraints
(Elsevier, 2015-01)
Structured sparsity approaches have recently received much attention in the statistics, machine learning, and signal processing communities. A common strategy is to exploit or assume prior information about structural ...
Detector de pontos salientes 3D baseado na DT-CWT com aplicação no posicionamento de malhas deformáveis em imagens de ressonância magnética do cérebro
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCCCâmpus São Carlos, 2019-08-30)
The magnetic resonance (MR) imaging is a noninvasive method that allows high soft tissue differentiation by providing a good anatomical detailing level. For this reason, the MR image is often used to help in diagnosis and ...
Implementación y evaluación de un filtro digital para la transformada wavelet compleja de doble árbol (dt-cwt) aplicada a fusión de imágenes bidimensionales en escala de gris
(2010)
La teledetección aplicada a las geo-ciencias es una herramienta que ofrece un costo relativamente bajo para la detección, clasificación y seguimiento de fenómenos terrestres. Muchos de sus sensores ofrecen imágenes de media ...
