Pedestrisan information, which implies the number, position, speed, and direction of them, is needed for management of public facilities. From this information, we obtain traffic density and coefficient of utilization of facilities in detail. In case of emergency, it can offer the information for evacuation. But recently counting of pedestrian has been acheived by hand or special gate. The purpose of this study is to propose two methods : 1) Monitoring of pedestrian by image processing, and 2) Removing shadow of pedestrian in image. The method 1) is performed by using serial difference of image, we can get the number and position of pedestrian, and from sequencial image data we reckon their speed and direction. The shadow of pedestrian makes error in counting number of them, therefor method 2) is needed to obtain accurate number. In conclusion, we can remove the shadow, and if the number of pedestrian is under 20 per 10 meters around, we can trace each pedestrian.
