Face detection and tracking in real time sequence of images independent of environment illumination

One of important topics in image processing and machine vision is face detection and tracking. There are problems and difficulties into face detection and tracking scope, for example: change environment illumination, presence glasses and beard on the face. In this paper, one hardware system based on infrared light is designed and implemented to solve these problems. In proposed method after face detection, bright face image (illuminated face image by infrared light) is subtracted from dark face image, and then face tracking is done by following rectangular frame on face. The proposed method regardless solving problems, has benefits such as: simplicity, good performance and accuracy and low computational cost (proper for real time applications). The described system, unlike many existing methods that are laboratorial, has been implemented and tested in a real environment.
