This is a fork from the Legit library, in an attempt to decouple it's internal LGT vision tracker.
Description from legit:
LGT - a C++ port of the LGT tracker as described in TPAMI paper "Robust Visual Tracking using an Adaptive Coupled-layer Visual Model". More details available here. The code is in some sections different from the official Matlab implementation so the results may be different.
The core of the library is under BSD license. Tracker implementations are licensed under different licenses.
