タイトル Two-Dimensional Fourier Image Reconstruction (Inverse FT) Demo using Matlab
フリーキーワード FFT, Matlab, Spatial Frequency, Fourier Transform, Fourier Synthesis, Fourier Reconstruction, Inverse Fourier Transform
概要 IFFTDemo.m:

This Matlab script demonstrates the well-known fact that any arbitrary image
is a superposition of sine waves. This may be hard to believe for lay people
without a good demo.

Just run IFFTDemo.m. It first computes the Fourier transform of an image
using 2-dimensional FFT. The original image and its amplitude spectrum
are displayed in the top half of the window.
