A reason for the popularity of wavelets is their effectiveness in representation of nonstationary (transient) signals. The wavelet analysis is explained via a parallel with the Fourier analysis and short - time Fourier transform. discrete Fourier transforms; signal analysis; wavelet transforms...
Medical Image Fusion Algorithm Based on Nonlinear Approximation of Contourlet Transform and Regional Features As the most popular technique of the image fusion, the multiscale decomposition methods have developed quickly in recent years, such as discrete wavelet transform (DWT) [3, 7], framelet transf...
EEG signals are nonstationary; i.e., the frequency components present in the signal vary with time [1]. Diagnosis of Encephalopathy Based on Energies of EEG Subbands Using Discrete Wavelet Transform and Support Vector Machine Posteriormente, foram revisados todos os EEGs dos 175 funcionarios que...
