摘要：
In this paper, we describe a new polygraph system which is based on computer vision technologies. The underpinning idea is to detect pupil size variation from a sequence of images. Based on the variation of the pupil size, we can detect for truth or deception. We have experimented with our system and proved its effectiveness. Compared with traditional polygraph techniques, this is the best computer vision based system to date. It is much simpler compared to old systems and is easier to implement. © 2009 Bentham Science Publishers Ltd.
