System and method for using three dimensional infrared imaging to provide psychological profiles of individuals
First Claim
1. A computer implemented method for assessing a psychological state of a person, comprising:
- generating by a computer a sequence of three dimensional infrared imaged body maps of the person over an interval of time, the sequence being comprised of successive frames wherein the frame-to-frame interval is short enough to capture microexpressions;
processing by the computer the sequence to detect localized changes in temperature at a plurality of subsurface anatomical landmarks over the interval of time, said landmarks enabling pinpoint comparisons across the body maps in said sequence;
correlating by the computer localized frame-to-frame changes with one or more events during the time interval corresponding to the frame-to-frame changes; and
using the correlations between detected changes and corresponding events to assess the psychological state of the person.

Abstract
A sequence of three-dimensional thermal infrared images of the face or other area of the body is analyzed to extract time-varying maps which link skin surface temperature details to the locations of anatomical structures. Frame-to-frame quantitative variations in temperature and position of anatomical nodes of the body maps are determined for the sequence and compared to reference profiles to produce estimates of physiological condition and psychological state. The magnitude, latency, and duration of such variations at particular anatomical locations resulting from selected controlled stimuli have been determined to be strongly correlated with particular psychological states.

10. A computer implemented method for assessing interpersonal interactions, comprising:
-
generating by a computer a three dimensional infrared imaged body map sequence for each of two or more persons over an interval of time, each sequence being comprised of successive frames wherein the frame-to-frame interval is short enough to capture microexpressions; introducing a stimulus event during the time interval; detecting by the computer localized changes in temperature at a plurality of subsurface anatomical landmarks over the interval of time correlated to the stimulus in the body map sequence for each of the two or more persons, said landmarks enabling pinpoint comparisons across the body maps in each said sequence; and using the correlations between detected changes and corresponding events to assess the interpersonal interactions among the persons. - View Dependent Claims (11, 12)
