Feature recognition in images is one way to calibrate a digital camera. The algorithm of which this project will make use, which was written by a senior researcher at Microsoft Research, uses the measured locations of corresponding points in several images taken by a camera to find information about the camera itself. This project uses several prewritten modules to find features (in this case, easily detectable corners) in images, refine an estimate of their locations in 3-space, and calibrate the camera that took the images.
