Method and system for automatic identification using digital images
First Claim
1. A method for automatically identifying a person, comprising:
- obtaining results related to at least one skin condition from a UV image of a portion of a body surface of the person; and
comparing the results with prestored data associated with the at least one skin condition for a known person to determine if the person to be identified is the known person.

Abstract
The present invention provides a method and system for automatic identification (auto-identification). In one embodiment, a method for automatically identifying a person comprises acquiring white-light and UV images of a portion of the person'"'"'s skin, generating a skin mask from the white-light image, and comparing the skin mask with a pre-stored skin mask of the person. If a substantial match is not found between the two skin masks, the person is not identified, and an error message such as “wrong person” or “person unknown” is returned. Otherwise, the method proceeds to obtain results associated with certain skin conditions using at least the UV image. The results are compared with pre-stored results to determine if the person is the right person or wrong person.

24. A computer readable medium storing therein program instructions that when executed by a processor cause the processor to perform a method for automatically identifying a person, the program instructions comprising:
-
instructions for obtaining results related to at least one skin condition from a UV image of a portion of a body surface of the person; and
instructions for comparing the results with prestored data associated with the at least one skin condition for a known person to determine if the person to be identified is the known person. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31)

32. A system for automatic identifying a person using digital images, comprising:
-
an image acquisition device configured to acquire a white-light image and a UV image of a portion of a body surface of the person, each of the white-light and UV images having a plurality of pixels, each pixel in the UV image corresponding to a respective pixel in the white-light image;
a computer system configured to identify, on a pixel by pixel basis, skin-pixels in the white-light and UV images, and to obtain results associated with at least one skin condition using information in at least the UV image, the at least one skin condition including subsurface skin condition; and
a database storing skin condition data including subsurface skin condition data associated with a known person;
wherein the computer system is further configured to compare the obtained results with the stored skin condition results to determine if the person to be identified is the known person. - View Dependent Claims (33, 34)
