Human Stress Recognition from Facial Thermal-Based Signature: A Literature Survey

Abstract

Stress is a normal reaction of the human organism which triggered in situations that require a certain level of activation. This reaction has both positive and negative effects on everyone's life. Therefore, stress management is of vital importance in maintaining the psychological balance of a person. Thermal-based imaging technique is becoming popular among researchers due to its non-contact conductive nature. Moreover, thermal-based imaging has shown promising results in detecting stress in a non-contact and non-invasive manner. Compared to other non-contact stress detection methods such as pupil dilation, keystroke behavior, social media interaction and voice modulation, thermal-based imaging provides better features with clear boundaries and requires no heavy methodology. This paper presented a brief review of previous work on thermal imaging related stress detection in humans. This paper also presented the stages of stress detection based on thermal face signatures such as dataset type, thermal image face detection, feature descriptors and classification performance comparisons are presented. This paper can help future researchers to understand stress detection based on thermal imaging by presenting the popular methods previous researchers use for stress detection based on thermal images.

Privacy Enhanced Mobile User Authentication Method Using Motion Sensors

“…It usually uses learning methods to extract information representing user characteristics from different types of sensors on mobile devices to build a model. Such as face [6,7], fingerprint [8,9], voice [10,11], environmental location [12,13], keystroke behavior [14,15], finger movement [16,17], etc. However, the above-mentioned biometric information collection usually requires invoking the privacy-related permissions of the mobile device, which makes users worry that their privacy-related information may be leaked, and cannot take into account the security, privacy, and usability requirements of mobile authentication jointly at the same time.…”

Implementation of Thermal Camera for Human Stress Detection: A Review

“…Compared to previous review papers [14,15], we focused on comparing image acquisition and image processing on thermal images to detect stress in humans. This paper will also answer the research question: What types of analysis can be performed on stress detection data obtained using thermal cameras to identify human stress levels accurately?…”
