wrong fps in tracker.cpp

[pauloord123]

Tracker.cpp gives fps values only for the tracker->update, not for video.read() + tracker->update.

Better start with timer = (double)getTickCount(); just before the while(video.read) loop, and again at the end of that loop. Remove the timer from the first line in the loop.
This gives reasonable fps.

It's frame rate of tracker algorithm.
