FFT image filtering

Page demonstrating image filtering in the frequency domain using a 2D FFT

The Fourier image filtering page is an online demonstration of image filtering in the frequency domain. Upload your image and its 2D FFT frequency domain transform is shown. Draw on the FFT image using the rectangle, line or circle/arc tools (use the tool inverse to remove drawn areas) to remove certain frequencies then back transform using iFFT and view the filtered image.
