Abstract

The study on tracking of moving pedestrians based on video sequence has been presented in the paper. The video sequences have been processed by the background subtraction and adaptation, detection of moving objects, shadow detection, and image eroding and dilating in order to create the moving pedestrian contour. The change of location of the moving pedestrian contour and area has been considered in the method presented here. First, the method computed the centroid coordinates and radius of moving objects through the pedestrian contours. Second, the matching matrix has been established by the change of locations and radius between different moving pedestrians at two successive frames and the moving objects that matched each other have been found. The method has been tested using the video sequences of actual measurement, and the experimental results have been analyzed. Under the experiment condition, the contrails of moving pedestrians have been clearly drawn with a little noise at different image sampling intervals. Finally, the application condition of the method has been described.
