Abstract
Methods and systems are provided for performing a biometric function. A purported skin site of an individual is illuminated with illumination light. The purported skin site is in contact with a surface. Light scattered from the purported skin site is received in a plane that includes the surface. An image is formed from the received light. An image-texture measure is generated from the image. The generated image-texture measure is analyzed to perform the biometric function.
