Extracting sticker colors on Rubik's cube from video
Abstract
 This project tackles the problem of real-time object detection and localization. More specifically, we attempt to locate a Rubik’s Cube in a video stream and extract the sticker colors with minimal help from the user. The edge based approach we take is invarient to various camera settings and does not assume a particular color scheme for the cube.

The program is implemented as a single Python script. You need the OpenCV 2.1 Python bindings and numpy library.
This is research code so it is not pretty.

If your cube is black you can improve results by pressing 'b'.
