Abstract
Infrared and visual images are the two formats of a same image that to be identified in the gate control system. The infrared image is the reflection of the facial temperature feature, and the interferential signals such as the light can be removed in the image manipulation. The combination of the infrared image and the visual image increase the accuracy in the identification system. The mathematic arithmetic of the image manipulation for the facial features identification is suitable for both formats. The method of the identification is the pixels comparison. A facial image inputted from the video collection device is converted into an array of pixels in the identification system. The pixels that contain parts of the whole facial features are compared with those in an image database. Each of the infrared image and the visual image is calculated accordingly. In terms of the accordant degree of the two calculation results, the system can judge that whether the face belongs to a person in the database or not. Accordingly, the output signal can control the gate open or not.
