How can I know tracking is lost using KCF tracker

Question

I am using KCF tracker to track a region selected by hand (mouse). Once it is selected, the tracker is able to do it but the tracker fails to stop tracking after the target has moved outside the image.

Is there any way to know that the target region is lost or out of the image region.

try placing a conditional loop over the detected object. Once the object leaves it will stop tracking — Jeru Luke, Jan 07 '17 at 13:25

You can now use Tracker::update to detect whether the object is lost. This feature was just recently added (see https://github.com/opencv/opencv_contrib/pull/1123) and should land in the next release after 3.2.0.

Glad to hear this. I have been using detection which is a little bit slow. – user18441 Jun 12 '17 at 02:55
