Claim 10:
11. A system for camera-based stress determination of a human individual, the system comprising at least one processing unit and a data storage, the at least one processing unit in communication with the data storage and configured to execute:
a transdermal optical imaging (TOI) module to receive an image sequence capturing a body part of the human individual;
a data science module to process the captured image sequence, by a trained machine learning model, to determine a set of bitplanes of a plurality of images in the captured image sequence that represent hemoglobin concentration (HC) changes of the subject;
a reconstruction module to determine between heartbeats based on peaks in the set of bitplanes that represent HC changes of the subject and using the intervals between heartbeats to determine heart rate variability;
a stress module to determine a stress level using deviations of the heart rate variability; and
an output module to output the stress level.
