This app is an FFT camera.
The user takes a picture within the app, and the app displays the Fourier Transform of the image.
It also displays the inverse Fourier Transform (of the Fourier Transform), for when the user applies a low pass or high pass filter.
The filter is shown in the Fourier Transform image.
