Non-intrusive car driver's emotion recognition using thermal camera

Abstract

Several intrusive and non-intrusive techniques have been proposed in the past to monitor car driver's emotions but very little light was shed on using thermal cameras for such applications. This paper details with one such system that uses a single infrared thermal camera. Such a camera was used to overcome the issues pertaining to usage of single audio/visual sensors. Fusion of the outputs with the audio/visual sensors could provide a better ADAS (Advanced Driver Assistance System). The paper also details face detection techniques in each thermogram prior to emotion recognition.
