视频文件中人体步态特征的提取及应用研究

o apply gait recognition in the Passenger Identification System of the Gate, we extract the feature of human gait from the video which records a human in walking in special scene and apply it in the assignment of the sensors in the Passenger Identification System. Based on VC++6.0 and OpenCV, each frame of the video has been decoded and saved. And then, we use frame differential method to reject the background. After that, the foreground is threshold to get the contour of the human body. By recording and combining the contour in section, we obtain the XT section of human gait. At last, the simulation for the assignment of the sensors is performed. The results indicate that the feature is applied in the research of the assignment of the sensors successfully.
