2018-07-04 03:01:42 -0500 marked best answer Which is the best tracking algorithm available ?

Camshift, mean shift, BOOSTING, MIL, KCF, TLD, MEDIANFLOW are used for tracking objects within video sequences (It is available in OPENCV). I uses the above methods for my project but I am unsatisfied about result. Its accuracy about 60-70%. How to improve or other method?

Thanks!
