How to use KLT tracker in Visual Studio

edit

Hello ,I am trying to write a program that detects abnormality in crowded scenario. In which I first detected the interest points using Spatio-Temporal Interest Point Detector(STIP) and now would like to track the interest points using KLT tracker. But I don't know how to proceed with this. I tried to download KLT from here and Install but couldn't do it successfully. I would like seek some help( a guide) regarding how to install KLT tracker and use it to track Interest points.

I would like to use these motion vectors produced by KLT tracker to calculate the Interaction Energy Potentials for each Interest Point as Discussed in this paper
