2D-Fourier 1.4

2D-Fourier
2D Fourier calculates the two-dimensional Fourier transform of an image. Color images are first transferred to black/white. The Fourier image shows the amplitude of the complex kvectors along kx and ky axes. In complex setting the App shows the real and imaginary parts of k in red and blue, respectively.

Selected regions of the Fourier image can brushed out, or selected spatial frequencies can be added, and the effect on the...
