description: Point tracker based on pattern matching using an exhaustive search within an image region.
The Mask input is used to weight the pattern, so that only pixels from the Mask will be tracked.
The tracker always takes the previous/next frame as reference when searching for a pattern in an image. This can overtime make a track drift from its original pattern.
Canceling a tracking operation will not wipe all the data analysed so far. If you resume a previously canceled tracking, the tracker will continue tracking, picking up the previous/next frame as reference.
