Abstract
Tracking object in low frame rate video or with abrupt
motion poses two main difficulties which conventional
tracking methods can barely handle: 1) poor motion conti-
nuity and increased search space; 2) fast appearance varia-
tion of target and more background clutter due to increased
search space. In this paper, we address the problem from a
view which integrates conventional tracking and detection,
and present a temporal probabilistic combination of dis-
criminative observers of different lifespans. Each observer
