Abstract
Aiming at high time complexity of original tracking algorithm based on template matching technique and great computations of video image target tracking system, put forwards a matching and tracking method based on zero-mean normalized cross correlation based on early termination condition (ZNCC-ETC). Based on zero-mean normalized cross correlation with box-filtering (ZNCC-BF), there is a proper threshold in the matching process. Once the cross-correlation accumulation value between the template figure and candidate figure exceeds the proper threshold, any subsequent calculation is redundant, however, ZNCC-ETC method is able to realize image speed-up matching tracking by using early termination condition method, and the tracked result is verified and analyzed by comparing the experiments. The analysis results show that, comparing with standard ZNCC and improved ZNCC-BF, ZNCC-ETC can reduce the amount of calculation in the matching process, achieve the goal of speed-up matching and tracking on the premise of guaranteeing the global maximum convergence ability.关键词
