Nice demo Minimal options, but does what it says: displays the 2D Fourier transform of an image from your gallery or camera. You can edit the transformed image by blindly erasing out rectangles and observe the effect. Not much to it, and the UI is unpleasant, but it's a nice little demo.
Doesnt open image Rejects every image I tried to open from the gallery. (Wrong file format error message). Galaxy S3 running Android 6.0.1
Nice concepts, but lacks BASIC functions like "undo"

Many other bug fixes and optimizations
