]]> For the pixel manipulation assignment in Introduction to Computational Media, I created an edge finding algorithm that can find edges in the frames of a live video stream. The code is available on Github.

Below are some screen shots of the Processing sketch in action.

The script takes two images and applies the color histogram from the designated “source” image onto the designated “target” image.

Here’s an example with black and white images (photographs by Ansel Adams).
