Systems and methods for spoof detection based on local binary patterns

Abstract:

Disclosed are systems and methods for performing spoof detection. The method includes: receiving, by a processor from a biometric sensor, an input image of a biometric; analyzing the input image to identify pixels associated with a first feature in the input image; performing a local binary pattern (LBP) analysis on the pixels associated with the first feature, which comprises computing, for a given pixel associated with the first feature, an LBP value corresponding to texture of one or more neighboring pixels around the given pixel, wherein the neighboring pixels around the given pixel comprise eight pixels around the given pixel, including pixels on a top, a bottom, a left, a right, and at four corners of a location of the given pixel; and, determining whether the input image is a replica of the biometric based on results of performing the LBP analysis on the pixels associated with the first feature.
