SYSTEM AND METHOD FOR DETECTING INVISIBLE HUMAN EMOTION
First Claim
1. A system for detecting invisible human emotion expressed by a subject from a captured image sequence of the subject, the system comprising an image processing unit trained to determine a set of bitplanes of a plurality of images in the captured image sequence that represent the hemoglobin concentration (HC) changes of the subject, and to detect the subject'"'"'s invisible emotional states based on HC changes, the image processing unit being trained using a training set comprising a set of subjects for which emotional state is known.

Abstract
A system and method for emotion detection and more specifically to an image-capture based system and method for detecting invisible and genuine emotions felt by an individual. The system provides a remote and non-invasive approach by which to detect invisible emotion with a high confidence. The system enables monitoring of hemoglobin concentration changes by optical imaging and related detection systems.
