Automated Coin Detection on Android Phone

uses a Hough transform to determine the radius of coins while exploiting features such as the color of the penny. Overlapping coins and the presence of clutter are tolerated though the angle of the camera and the color of the background are restricted. Though the algorithm as it stands is slower than a human performing the same task, it is conceivable that in future work the methods described here could be scaled to a point where they find a real-world application in eliminating the need to manually count coins.
