3D ENHANCED IMAGE CORRECTION

摘要

A user authentication system and method. A two-dimensional image of a scene is obtained and range information obtained from the scene is aligned with the two-dimensional image. One or more depth regions is identified and image segments corresponding to the one or more depth regions are selected within the two-dimensional image. Brightness operations are performed on one or more of the selected image segments to form a corrected image.

1. A system for enhanced image correction, comprising:
a 2D camera; a 3D camera; and a processor to:
receive a two-dimensional image from the 2D camera;receive range information from the 3D camera;align the range information with the two-dimensional image;identify one or more depth regions;select, within the two-dimensional image, image segments corresponding to the one or more depth regions;perform brightness operations on one or more of the image segments to form a corrected image; andauthenticate a user based on a user feature in the corrected image.
