Abstract: Misjudgment on tracking status will result in the wrong template update strategy in mean-shift and loss the object.This article presents a novel tracking status analysis method.Firstly，through the comparison of features in target and background，a feature-enhancement function is introduced and a new background template is constructed based on it.Then，after comprehensive analysis of the dynamic changing process of each similarity coefficient during tracking，the proposed algorithm can accurately determines the tracking status and takes corresponding template update strategy.Experimental results show that the proposed algorithm can effectively enhance the tracking effect under complex condition and is more robust.

Key words: object tracking, mean-shift, tracking status analysis
