Imaging systems and methods for obtaining and using biometric information
First Claim
1. A method, comprising:
- generating two or more direct images of the body of a clothed subject by irradiating the subject with electromagnetic radiation selected to substantially penetrate clothing and to substantially reflect from the body of the subject, wherein each of the two or more direct images comprises spatial coordinate data associated with the surface of the body of the subject, and wherein the two or more images indicate movement of the body of the subject over time; and
using a computer, determining a motion signature from the two or more images, the motion signature being associated with the movement of the body of the subject.

Abstract
Disclosed herein are exemplary embodiments of imaging systems and methods of using such systems. In one exemplary embodiment, one or more direct images of the body of a clothed subject are received, and a motion signature is determined from the one or more images. In this embodiment, the one or more images show movement of the body of the subject over time, and the motion signature is associated with the movement of the subject'"'"'s body. In certain implementations, the subject can be identified based at least in part on the motion signature. Imaging systems for performing any of the disclosed methods are also disclosed herein. Furthermore, the disclosed imaging, rendering, and analysis methods can be implemented, at least in part, as one or more computer-readable media comprising computer-executable instructions for causing a computer to perform the respective methods.

12. One or more computer-readable memory components storing computer-executable instructions for causing a computer to perform a method, the method comprising:
-
receiving two or more direct images of the body of a clothed subject, wherein the two or more images are generated by irradiating the subject with electromagnetic radiation selected to substantially penetrate clothing and to substantially reflect from the body of the subject, wherein each of the two or more direct images comprises spatial coordinate data associated with the surface of the body of the subject, and wherein the two or more images indicate movement of the body of the subject over time; and determining a motion signature from the two or more images, the motion signature being associated with the movement of the body of the subject. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 27)
