Abstract
A method of determining physiological indices for a remote polygraph test, which may include, using a computing device operating a processor: receiving a video of a face of a subject; based on the video, monitoring a plurality of physiological indices of the subject; and based on values of the monitored physiological indices and a physiological correlation between the monitored physiological indices, determining a plurality of corrected physiological indices, the corrected physiological indices having values that are consistent with each other to reflect a consistent physiological condition of the subject.

A method of determining physiological indices for a remote polygraph test, the method comprising, using a computing device operating a processor:
- receiving a video of a face of a subject;
- based on the video, monitoring a plurality of physiological indices of the subject;
- and
- based on values of the monitored physiological indices and a physiological correlation between the monitored physiological indices, determining a plurality of corrected physiological indices, the corrected physiological indices having values that are consistent with each other to reflect a consistent physiological condition of the subject;
- wherein the monitoring of the plurality of physiological indices comprises:
- based on a dataset comprising data values indicative of a variation in time of a color of pixels in a selected region of the face, determining a heart rate spectrogram and a respiratory rate spectrogram;
- and
- based on the heart rate spectrogram and the respiratory rate spectrogram, determining an oxygen saturation of the subject.
A method of determining physiological indices for a remote polygraph test, the method comprising, using a computing device operating a processor:
- receiving a video of a face of a subject;
- based on the video, monitoring a plurality of physiological indices of the subject;
- based on values of the monitored physiological indices and a physiological correlation between the monitored physiological indices, determining a plurality of corrected physiological indices, the corrected physiological indices having values that are consistent with each other to reflect a consistent physiological condition of the subject;
- and
- providing the corrected physiological indices as an input to a remote polygraph test system, wherein remote polygraph test system comprises a processor to determine, based on the corrected physiological indices, whether the subject in video is truthful or deceptive in their answers to test questions;
- wherein the corrected physiological indices comprise a first subset comprising corrected values of a first subset of the monitored physiological indices, and a second subset of non-corrected values of a second subset of the monitored physiological indices, the corrected values and the non-corrected values being consistent with each other.
