Basic Tracker Requirements
The prospective trackers must meet several basic requirements, as described in the requirements section of the panel. These include a minimum length (measured in frames), and an amplitude, plus average and peak errors.
The amplitude is a value between zero and one, describing the change in brightness between the tracker center and background. Larger values will require more pronounced trackers.
The errors numbers measure the distance between the 2-D tracker position and the computed 3-D position of the tracker, mapped back into the image. The average error limits the noisiness and jitter in the trackers, while the peak error limits the largest “glitch” error. Notice that these controls do not change any trackers, but instead select which of the prospective trackers are actually selected for addition.
You can ask for only spot trackers, only corner trackers, or allow trackers of either type to be created.
