Determinacão do período orbital de sistemas binários clipsantes
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em FísicaFísica da Matéria Condensada; Astrofísica e Cosmologia; Física da Ionosfera, 2009-08-27)
In this work is presented a new method for the determination of the orbital period (Porb) of eclipsing binary systems based on the wavelet technique. This method is applied on 18 eclipsing binary systems detected by the ...
A 2-D Continuos Wavelet Transform method for InSAR phase-maps Denoising
(SPIE, 2013-07)
Analysis of Interferometric Synthetic Aperture Radar (InSAR) phase–maps with large wide band is still a challenging problem that requires the development of robust methods. This paper presents a 2–D Continuous Wavelet ...
3D shape measurement with temporal phase unwrapping and 1-D continuous wavelet transform
(SPIE, 2021-03)
The correct phase unwrapping in the presence of noise is a di cult problem and it has been of great interest since the last decades as observed in the literature. This is due to the spatial dependency that exists in ...
