针对在静态背景视频中行人检测和跟踪时受行人运动状态影响较大,容易产生误识别,提出了一种基于位置特征的运动行人检测与跟踪方法.检测阶段得到运动行人的二值化差分图后,引入水平融合值、垂直融合值将满足融合要求的非连通区域外接矩形融合得到一个新矩形,以新矩形及其中心作为行人的位置特征,对行人进行检测与跟踪.用该方法跟踪行人视频中的两个行人,跟踪准确率分别为98%与95%.
針對在靜態揹景視頻中行人檢測和跟蹤時受行人運動狀態影響較大,容易產生誤識彆,提齣瞭一種基于位置特徵的運動行人檢測與跟蹤方法.檢測階段得到運動行人的二值化差分圖後,引入水平融閤值、垂直融閤值將滿足融閤要求的非連通區域外接矩形融閤得到一箇新矩形,以新矩形及其中心作為行人的位置特徵,對行人進行檢測與跟蹤.用該方法跟蹤行人視頻中的兩箇行人,跟蹤準確率分彆為98%與95%.

In this paper, a method of detecting and tracking moving pedestrians is studied,based on position features in static scenes, to solve problem of fluctuated image caused by moving that can easily resulted in false identification. Firstly getting the binary image segmentation of moving pedes-trian during the process of tracking, then introducing horizontal merging value, vertical merging val-ue to merge the contour-rectangle of some separated areas, lastly taking the new rectangle and its center as the position character of moving pedestrian to detect and track moving pedestri-an. Experimental results of two moving pedestrians' scenes show that 98% of one pedestrian can be detected and tracked and the other is 95%.
