The discrete Fourier transform with reduced spectral leakage and its applications in image processing
碩士 === 元智大學 === 光電工程學系 === 103 === Discrete Fourier transform (DFT) calculates the spectrum of a signal. The computation cost of DFT can be effectively reduced by the use of the fast Fourier transform (FFT) algorithm. The frequency sampling of FFT is equally spaced. When a signal comprises a frequen...
