About Fourier Filter Camera

Draw image filters with your fingers! This Application provides an interface for viewing the Fourier Transform of a scene using your device's camera, as well as drawing a virtual aperture using your fingers. This was developed as part of a class project for a Computational Photography Class at UC Berkeley.

Two dimensional Fourier Analysis can be a difficult thing to understand - however, it is central to developing an understanding of both imaging systems and image processing techniques. This application should provide the same intuition as an introductory MATLAB programming assignment related to two-dimensional Fourier Transforms.

Fourier Filter Camera requires the OpenCV Android library, which is now included in the app itself.

This application is open-source. Repository is here: https://github.com/zfphil/FourierFilterCam

What are users saying about Fourier Filter Camera

by X####:

This is by far the nerdiest app I've seen so far, I love it! The only drawback is that it is not possible to save the fourier images directly and that when saving images the filter is not applied.

Z70%
by Z####:

Displays a *live* 2D Fourier transform from your device's camera, color or black and white. Even more cool, you can filter the image in Fourier space: freehand draw your own low-pass, high-pass, anisometric filters. A fun and visual way to get an intuition for this efficient and powerful method.
