タイトル Two-dimensional spatial frequency filtering by FFT using Matlab
フリーキーワード Matlab, FFT, Fourier Tansform, Spatial Frequency, Filtering
概要 Matlab scripts for band-pass filtering a 2-dimensional image using FFT. One does isotropic filtering. The second one performs oriented band-pass filtering similar to an array of simple cells in V1.
