This paper reports a summary of the 14th algorithm contest entitled "Lock on targets! -- object tracking --". This contest is supported by PRMU (Pattern Recognition and Media Understanding) technical group of IEICE-ISS. In this paper, brief overviews of prize-winning algorithms are presented by the winners. The contest in this year asks fast and accurate algorithms to track objects from videos. 73 algorithms were submitted to this contest (2nd largest submissions among the past contests), and 7 algorithms had won the prizes.
