摘    要:为了快速准确跟踪运动目标,提出了基于K-S(kolmogorov-smirnov)检验的直方图匹配目标跟踪算法。将直方图信息作为模板,通过Kalman滤波原理预测出目标下一时刻的可能出现位置,以该位置为中心确定一个搜索范围,在搜索范围内判别直方图的相似性并进行模板匹配,在当前图像中跟踪目标。结果表明,基于K-S检验的直方图匹配方法可减小搜索范围,利用Kalman滤波预测目标的位置,在预测位置附近进行模板匹配,可有效减少模板匹配的遍历时间,提高目标实时跟踪效率。

关 键 词:K-S检验  直方图  模板匹配  目标跟踪  Kalman滤波

Abstract:A histogram matching target tracking algorithm based on K-S(kolmogorov-smirnov)test is proposed for the purpose of tracking moving targets accurately and rapidly.The histogram information can be taken as the template.The possible position of the target at the next moment is predicted by Kalman filter Principle.A search scope can be ascertained by taking the forecast position as the center,in which K-S test principle is applied to judge the similarity of histograms.Template matching is realized based on histogram information,which can search the tracking target in the current image.The results indicate that target can be tracked accurately and quickly by the histogram matching method based on K-S test,and instead of global scope,template matching is realized near the forecast position predicted by Kalman filtering,which can reduce ergodic time of template matching and improve the efficiency of the real time target tracking.
Keywords:K-S test  histogram  template matching  target tracking  Kalman filtering
