WebNov 1, 2014 · The mean-shift procedure is a popular object tracking algorithm since it is fast, easy to implement and performs well in a range of conditions. We address the problem of scale adaptation and present a novel theoretically justified scale estimation mechanism which relies solely on the mean-shift procedure for the Hellinger distance.
