Abstract
Abstract Thermal image data of at least a region of a face of a person is provided. The thermal image data is used to determine a physiological state of a person, e.g., anxiety. For example, anxiety may be determined by a comparison of the thermal image data to a baseline, or by comparison of thermal image data for one region of the person's face to another.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
78 words
A method to detect a physiological state of a person, the method comprising: providing thermal image data of at least a region of a face of a person, wherein providing the thermal image data comprises providing thermal image data of at least a periorbital region of an eye of the person representative of blood flow to at least eye musculature in the periorbital region; and using the thermal image data to determine a physiological state of the person.
Claim 2
Independent Claim
78 words
A method to detect a physiological state of a person, the method comprising: providing thermal image data of at least a region of a face of a person, wherein providing the thermal image data comprises providing thermal image data of at least a periorbital region of an eye of the person representative of blood flow to at least eye musculature in the periorbital region; and using the thermal image data to determine a physiological state of the person.
Claim 3
Dependent Claim
24 words
The method of claim 1 , wherein using the thermal image data comprises using the thermal image data to determine anxiety in the person.
Claim 4
Dependent Claim
32 words
The method of claim 2 , wherein using the thermal image data comprises detecting a change, over a plurality of frames, in the thermal image data when the person is experiencing anxiety.
Claim 5
Dependent Claim
78 words
The method of claim 1 , wherein providing the thermal image data comprises providing thermal image data of at least the periorbital region of the eye of the person and of another region of the face, and further wherein using the thermal image data to determine the physiological state of the person comprises comparing the thermal image data of the periorbital region of the eye of the person to thermal data of the other region of the face.
Claim 6
Dependent Claim
20 words
The method of claim 4 , wherein the other region of the face comprises a cheek region of the face.
Claim 7
Dependent Claim
22 words

The method of claim 1 , wherein providing thermal image data of at least a region of a face of a person comprises: providing thermal image data of a scene; and selecting thermal image data of the face of the person from the thermal image of the scene.
Claim 10
Dependent Claim
60 words
The method of claim 1 , wherein providing thermal image data of at least a region of a face of a person comprises: providing thermal image data of a face of the person; and identifying thermal image data for one or more regions of the face based on at least bilateral symmetry of the thermal image data of the face.
Claim 11
Dependent Claim
83 words
A detection system to detect a physiological state of a person, the system comprising: a thermal infrared image device operable to provide thermal image data of at least a region of a face of a person, wherein the region of the face comprises at least a periorbital region of an eye of the person representative of blood flow to at least eye musculature in the periorbital region; and circuitry operable upon the thermal image data to determine a physiological state of the person.
Claim 12
Dependent Claim
83 words
A detection system to detect a physiological state of a person, the system comprising: a thermal infrared image device operable to provide thermal image data of at least a region of a face of a person, wherein the region of the face comprises at least a periorbital region of an eye of the person representative of blood flow to at least eye musculature in the periorbital region; and circuitry operable upon the thermal image data to determine a physiological state of the person.
Claim 13
Dependent Claim
26 words
The system of claim 10 , where in the Circuitry is operable upon the thermal image data to determine the presence of anxiety in the person.
Claim 14
Dependent Claim
31 words
The system of claim 11 , wherein the circuitry is operable to detect a change, over a plurality of frames, in the thermal image data when the person is experiencing anxiety.
Claim 15
Dependent Claim
