Request/reply: Set tracking color. For some sensors (ie CMUcam), simple blob tracking tracks only one color. To set the tracking color, send a PLAYER_BLOBFINDER_REQ_SET_COLOR request with the format below, including the RGB color ranges (max and min). Values of -1 will cause the track color to be automatically set to the current window color. This is useful for setting the track color by holding the tracking object in front of the lens. Null response. |

Configuration request: Set imager params. Imaging sensors that do blob tracking generally have some sorts of image quality parameters that you can tweak. The following ones are implemented here:
