  annote =      {The mean-shift procedure is a popular object tracking
                  algorithm since it is f ast, easy to implement and
                  performs well in a range of conditions. We address
                  the problem of s cale adaptation and present a novel
                  theoretically justified scale estimation mechanism
                  which relies solely on the mean-shift procedure for
                  the Hellinger distance. We also propose two impro
                  vements of the mean-shift tracker that make the
                  scale estimation more robust in the presence of
                  background clutter. The first one is a novel
                  histogram color weighting that exploits the object
                  neighborhood to help discriminate the target called
                  background ratio weighting (BRW). We s how that the
                  BRW improves performance of MS-like tracking methods
                  in general. The second improvement boost the
                  performance of the tracker with the proposed scale
                  estimation by the introduc tion of a
                  forward-backward consistency check and by adopting
                  regularization terms that counter two major
                  problems: scale expansion caused by background
                  clutter and scale implosion on self-similar
                  objects. The proposed mean-shift tracker with scale
                  selection and BRW is compared with recent
                  state-of-the-art algorithms on a dataset of 77
                  public sequences. It outperforms the re ference
                  algorithms in average recall, processing speed and
                  it achieves the best score for 30% of the sequences
                  - the highest percentage among the reference
                  algorithms.},
