An analysis of TZSearch algorithm in JMVC

In this paper, we research and analyse TZSearch fast algorithm in JMVC. We first introduce the principle and implementation process of the TZSearch, then statistic and summarize the distribution of best matching points; finally, according to analyse of statistic results and the optimal threshold set, set up corresponding threshold for different video feature, early terminate the algorithmic process to reduce the computational complexity. Experiments show that the setup of the threshold set is reasonable, the effect of the proposed algorithm in saving computation time is prominent, and finally sum up the general rule of different characteristics video images applying to different thresholds.
