Fourier Filter Camera

अपनी उंगलियों का उपयोग कर अपने खुद का कैमरा एपर्चर ड्रा!

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
