Fourier Transform

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,...

This is an old program (1.999) that I have written for understanding radiation patterns of antennas. Basically I was looking for the relationship between interference diagram (Fourier transform of ilumination, usually called Array Factor) and 3D radiation pattern of the Array. For that reason, it...
