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.<br /> This was made as a Grasshopper plugin playing with System.Drawing.Bitmaps retrieved from a webcam.
