New biological real-time pattern extraction method emulating fly's behavior

We propose a biological real-time pattern extraction method. In order to extract objects from a frame image taken by a camera, many virtual flies (VFs) scattered in the CRT display are utilized. An individual VF composed of 3/spl times/3 pixels can freely fly in the display. A fundamental object extraction method is to detect objects just like flies sensing foods and swarming around them. The methodology realized by the soft computing technology and experimental results are described in detail.
