CWT x DWT x DTWT x SDTWT: Clarifying terminologies and roles of different types of wavelet transforms
(2020-01-01)
Wavelets have been placed at the forefront of scientific researches involving signal processing, applied mathematics, pattern recognition and related fields. Nevertheless, as we have observed, students and young researchers ...
Fusing time, frequency and shape-related information: Introduction to the Discrete Shapelet Transform's second generation (DST-II)
(2018-05-01)
This article introduces the second generation of the Discrete Shapelet Transform (DST-II), a tool created for fusing three types of information: time, frequency and shape-related. Considered a particular Discrete Wavelet ...
Classificação de estágios de sono através da aplicação de transformada wavelet discreta sobre um único canal de eletroencefalograma
(Universidade Federal de Santa MariaBrasilCiência da ComputaçãoUFSMPrograma de Pós-Graduação em Ciência da ComputaçãoCentro de Tecnologia, 2016-01-25)
The correct sleep stage classification allows sleep experts to diagnose and treat disorders
such as apnea, narcolepsy and insomnia. Such task is classically performed by sleep
medicine experts, where one or more physiological ...
Adaptive seismic ground roll attenuation using the double density dual tree discrete wavelet transform (dwt) method
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2012)
Seismologists working on the reflection of seismic data have been dealing with noise and trying to attenuate noise as much as possible without damaging a particular signal. Many methods have been used to removenoise types, ...
Comparative Analysis of Wavelet and EMD in the Filtering of Radar Signal Affected by Brown Noise
(IEEE, 2013-02)
In Electronic Warfare the goal of the attacker is
interfering with communications of his adversary. A common
type of attack is Jamming which corrupts the electronic devices s
signals by introducing intentionally different ...
