Real-time image processing of a live video stream using OpenGL ES on iOS devices.

The purpose of this app was to evaluate the feasibility of edge detection techniques as an accessibility tool. While the screen size and form-factor of iOS devices is not conducive to real-world use, this was intended as a early prototype to test generating an accessible video stream from a cell phone camera. As a result, the selection of filters is somewhat narrow in scope and is centered around providing meaningful ways of either enhancing a live video stream (by highlighting object edges) or transforming it entirely into a format that is easier for persons with reduced vision to see. 

The source code is available on GitHub.
