Problem when rotating the model

[lanyusea]

Hi, thanks for building the C++ version OpenTLD

I just found a problem when I tested it today.

I marked the model, which is a logo on my cup. When I rotate the cup, the box covering the model became smaller and smaller until the model cannot be seen in the sight. At that moment, the box became cover and follow the edge of my cup and the background.

I think it should be caused by the learning procedure of the algorithm. and to solve that I need to add a threshold of the recall value. but due to the large number of files, can anyone give me an idea what file should I modify?

I find a TODO in line 78 of file MedianFlowTracker.cpp, but not sure whether this related and how to change it.
