BlackTrack looks for the brightest and darkest pixel within a video image and outputs their coordinates. Only specified grid points are taken into account to have scalable performance/resolution.

future implementation:

• video image mask to surpress certain areas
• background subtraction
• multiple points

Whats the point of this plugin? Well, i often use such low-level processing to track things. Take a videoinput, mask the nonsense, do background subtraction and track the rest. And all of this with little cpu consumption and quite reliable.

common application is headtracking with a ceiling cam.
