Detailed Description

CMUcam4 tracking data structure.

The middle mass is also called the centroid and is the average position of all the tracked pixels in the image. The bounding box surrounds all the tracked pixels in the image. The pixels value can be used to infer the size or distance of the color blob of tracked pixels - the higher the pixels then the larger or closer the color blob. The confidence value can be used to infer the density or quality of the lock on the target color blob of tracked pixels - the higher the confidence then the better the lock on the color blob.
