Adaptive visual color tracking

This is a brief demo of visual color detection method that I wrote about two years ago. After an initial calibration phase, where one has to manually specify the color to be detected (in this case: green), the "Auto Detection" mode is switched on. In this mode, the color for which it is being scanned is updated in each iteration based on the colors found. This allows for more robust detection under changing light conditions.
