To countt the passing people through the gate of the buildings or the entertainment halls is considered important for the office security or the marketing researches. In this paper, an automatic counting method of the passing people by utilizing color information is proposed. First, in the proposed method, the color images of the passing people are obtained in series. As a next step, pixels on an angled measurement line are picked up and arranged along the time axis. As a result, a space-time image which includes just the data of the passing people over the angled measurement line is generated. On this space-time image, the the distribution shape of the incoming persons is different from that of the outgoing persons. By detecting the distribution shape of the people data, the moving direction of the passing people can be recognized. Finally, each number of the incoming persons and the outgoing persons could be measured by counting the people data with each direction information. In this paper, we describe the algorithm of counting the passing people using the two space-time images and show some experimental results obtained by using a simple experimental system to verify effectiveness of the proposed method.
