Patent Images
1. A method for use in detection of a person disguised with one or more artificial materials, the method comprising:
- detecting reflection from at least one portion of a head of a human body in at least a portion of an upper band of the near infrared spectrum; and
determining the presence of an artificial material associated with the head of the human body based on the detected reflection.

Abstract
Detection of a person disguised with one or more artificial materials includes detecting reflection from at least one portion of a head of a human body in at least a portion of an upper band of the near infrared spectrum. The presence of an artificial material associated with the head of the human body is determined based on the detected reflection.

16. A disguised person detection system comprising:
-
a detector apparatus operable to detect reflection from at least a portion of a head of a human body in at least a portion of an upper band of the near infrared spectrum; and
an indication apparatus operable to provide a user with information as to the presence of an artificial material associated with the head of the human body based on the detected reflection.

29. A detection method comprising:
-
detecting reflection from a scene in at least a portion of one band of the near infrared spectrum;
determining the presence of a head of a human body in the scene based on the detected reflection in the at least a portion of the one band of the near infrared spectrum;
detecting reflection from at least one portion of the head of the human body in at least a portion of an upper band of the near infrared spectrum to determine the presence of an artificial material associated with the head of the human body based on the detected reflection from at least one portion of the head of the human body.
