Spectrogram analysis of selected tremor signals using short-time Fourier transform and continuous wavelet transform
spectrogram wavelet transform broadband tremor
2015/10/8
Among a variety of spectrogram methods Short-Time Fourier Transform (STFT) and Continuous Wavelet Transform (CWT) were selected to analyse transients in non-stationary tremor signals. Depending on the...
Power Tensor Theory and Continuous Wavelet Transform
Wavelets Tensor Electrical Power Power Electronic Power Quality
2013/1/30
A model for the definition of electrical Power is presented, which retrieves the concepts of homomorphism from the geometrical tensor approximation at the wavelet approach. Their definition here is ne...
The fast Fourier Transform and fast Wavelet Transform for Patterns on the Torus

2011/9/21
Abstract: We introduce a fast Fourier Transform on regular d-dimensional lattices. We investigate properties of congruence class representants, i.e. their ordering, to classify directions and derive a...
Application of the cross wavelet transform and wavelet coherence to geophysical time series
cross wavelet transform wavelet coherence geophysical time series
2009/11/11
Many scientists have made use of the wavelet method in analyzing time series, often using popular free software. However, at present there are no similar easy to use wavelet packages for analyzing two...
Rotation-Invariant Texture Analysis and Classification by Artificial Neural Networks and Wavelet Transform
Texture Wavelet transform Artificial neural networks Classification
2009/10/13
A large number of approaches for texture analysis have been suggested for the purpose of texture classification. Recently, wavelet frames were proposed for texture features extraction. In this study, ...
Quantum computation of multifractal exponents through the quantum wavelet transform
Quantum computation multifractal exponents quantum wavelet transform
2010/4/7
We study the use of the quantum wavelet transform to extract efficiently information about the multifractal exponents for multifractal quantum states. We show that, combined with quantum simulation al...

INVERSE RADON TRANSFORM WITH ONE-DIMENSIONAL WAVELET TRANSFORM
Radon transform wavelet tran
2007/12/10
In this paper, the wavelet inverse formula of Radon transform is obtained with onedimensional wavelet. The convolution back-projection method of Radon transform is derived from this inverse formula. ...
