Lie Detector with Eye Movement and Eye Blinks Analysis Based on Image Processing using Viola-Jones Algorithm

Abstract

Nowadays, many lies occur and should be noticed and uncovered. However, there are various purposes to lie. Sometimes a lie causes many issues, especially for important things, and needs massive people like business, criminality, and other important things. The author uses The Viola-Jones method, which can detect faces, eye images, and changes in the eyes. Compared with fuzzy logic, this method could give more than 50% of accuracy. From a research and system analysis, 30 respondents are given five questions for each person. This system detection obtained an average of 91.07% accuracy for proper eye movements while 85.30% for flicker eyes. Hence, in total research for system detection of respondents is the accuracy of 78%, the precision of 77%, and the recall of 80% with 117 correct answers from 150 questions for 30 respondents.
