Lie Detection

The aim of this book is to propose an automated system based on facial gestures which can be built and will be more robust and reliable as compared to the techniques already being used for deception detection.Research has shown that in contrast to polygraph tests detecting deception through gestures will be more flexible because we need not to attach sensors to the body or any other equipment.Humans might not be able to track such micro-expressions which can detect deception but computers can because of their fast processing speed.
