Fourier Analysis

GFourier can help you use Fourier Analysis for image restoration. GFourier calculates the Fourier Transform of a given image and allows the use of filters in the frequency domain. The Inverse Fourier Transform is then used to substitute original image.. Get GFourier at SourceForge.net. Fast,...

Finding the Fourier transform of a rectangular pulse..filtering the spectrum and regenerating the signal usingthe filtered spectrum is done...at the end Rayleigh theorem is proved by showing that the energy content of both time domain and frequency domain signals are equal..your comments are...

GFourier is a plug-in for GIMP; with GFourier, you can use Fourier Analysis, to enhance and recover your images. More specifically, GFourier calculates the Fourier Transform of an image; you can then design and apply some simple filters; later, you can use the Inverse Fourier Transform to...

For several different reasons it could occur that we need to produce a signal from the sum of several harmonic components. In the usual case of Fourier analysis, FFT and IFFT are likely the best choice. However it could happen that:- The frequencies of the harmonic components are unevenly spaced-...
