USE OF RELATIVELY PERMANENT PIGMENTED OR VASCULAR SKIN MARK PATTERNS IN IMAGES FOR PERSONAL IDENTIFICATION

摘要

Embodiments include methods, devices, software, and systems for identifying a person based on relatively permanent pigmented or vascular skin mark (RPPVSM) patterns in images. Locations of RPPVSMs in different images of people are point matched, and a correspondence probability that the point matched RPPVSMs are from different people is calculated. Other embodiments are also described. Other embodiments are also described and claimed.

主权项

1. A method comprising:
point matching a first plurality of RPPVSMs in a first image with a second plurality of RPPVSMs in a second image; and determining a correspondence probability between the first plurality of RPPVSMs and the second plurality of RPPVSMs based on using variables comprising: a size of overlapped total skin area of two images containing RPPVSMs, a distance threshold between two RPPVSMs to be considered matching, and a number of matching RPPVSMs of the first and second images, wherein one of the point matching or the determining is performed by a processor.
