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

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.
