difference between eval_motchallenge and evaluateTracking

[songsonha]

Sorry because I have a dummy question. But I don't really understand what is the difference between eval_motchallenge and evaluateTracking module. Can someone answer that for me pls?
2. question: what is the difference between MOT16/17 and Motchallenge? There are some different purposes for them?

I think I can answer question 1

Good question, actually! Wondered about it myself :) eval_motchallenge was written by myself as a general purpose evaluation for motchallenge metrics. Later evaluateTracking was added, because some MOT challenges (MOT16/17) required special preprocessing of the provided files (removing mostly hidden ground-truth etc.)

Seems like a lot of code got duplicated in that commit. So if you feel like codensing the apps into single application feel free to submit a PR.
