Fourier Filter Camera
Free AppAbout 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

App History & Updates
What's Changed
Updated OpenCV to version 3.1, which provides performance improvements and big fixes. Also included library in application (should fix issues with opencv loader). This should improve compatibility with Android 4.x devices.

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.

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.
