Why the study?
Does multispectral imaging technology accurately classify physical and emotional stress?
Does multispectral imaging technology accurately classify physical and emotional stress?
Multispectral imaging of the facial region can classify physical and emotional stress with over 90% accuracy, offering a potential noninvasive stress monitoring tool.
May support noninvasive stress monitoring; hypothesis-generating and requires prospective clinical validation.
The stress classification algorithms are proposed based on multispectral imaging (MSI) system in this study. By extracting spectral features from the facial region, it is feasible to arrive at some quantity which can be related to the physiological property or functionality. The proposed method has been tested, and the accuracy for the classification of physical stress (PS) and emotional stress (ES) is over 90% by using the MSI techniques. Therefore, the classification feature of emotional stress and physical are successfully obtained. Experiments show that the classification result is encouraging, and the highly successful rate stems from the fact that the manipulated spectral quantity agrees with the physiological ground truth very closely. This study can lead to a practical system for the noninvasive classification of stress states.
