A method for counting passersby using time-space image

Recently, there are many serious crimes happening in many institutions and commercial areas. Therefore, security and protection for those areas are needed. This paper proposes an automatic method for counting passersby using horizontal measurement line to solve this serious problem. In this paper, time and direction information are used to count passersby. Therefore, time-space image and measure the speed of each passerby with determination of their distance are applied. In our experiment, the camera is fixed on the front of the hall. A PC is connected to the camera with a frame rate 17 frame per second. Finally, our experimental results prove the effectiveness of our method.
