Deception detection system and method
First Claim
1. A system for detecting deception for the security screening of a person of interest by an attendant, the system comprising:
- a camera configured to capture an image sequence of the person of interest;
a 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 person, to detect the person'"'"'s invisible emotional states based on HC changes, and to output the detected invisible emotional states, the processing unit being trained using a training set comprising HC changes of subjects with known emotional states; and
,a notification device for providing a notification of at least one of the person'"'"'s detected invisible emotional states to the attendant based on the output of the processing unit.

Abstract
A system for detecting deception is provided. The system comprises a camera, an image processing unit, and a notification device. The camera is configured to capture an image sequence of a person of interest. The image processing unit is 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 person, and to detect the person'"'"'s invisible emotional states based on HC changes. The image processing unit is trained using a training set comprising a set of subjects for which emotional state is known.

10. A method for detecting deception for the security screening of a person of interest by an attendant, the method comprising:
-
capturing, by a camera, an image sequence of the person of interest; determining, by a processing unit, a set of bitplanes of a plurality of images in the captured image sequence that represent the hemoglobin concentration (HC) changes of the person, detecting the person'"'"'s invisible emotional states based on HC changes, and outputting the detected invisible emotional states, the processing unit being trained using a training set comprising HC changes of subjects with known emotional states; and
,providing a notification, by a notification device, of at least one of the person'"'"'s detected invisible emotional states to the attendant based on the output of the processing unit. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
