DVO Tracker

348

UM-2014.1-07

If tracking fails because our tracked feature loses definition or goes out of

camera, we can enable Predict Tracking at this point.

When we resume tracking, the track path is calculated such that it smoothly

continues along the same path as calculated previously.

1: Tracking ...

2: Feature reaches edge of frame. Turn Predict

Tracking ON.

3: Feature off camera but track path is

extrapolated.

Track path extrapolation continues.

Reference

The DVO Tracker is available to use everywhere we have a Shapes layer

available. As such, we can draw a shape to define the feature we wish to

track and use the result as a Region of Interest matte.
