Fourier Filter Camera

Draw your own camera Aperture using your fingers!

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
