Abstract
A vision-based operating system is provided in which a computer-based system accepts visual inputs and takes appropriate actions in a wide variety of environments. One environment is a security environment in which the vision-based operating system acquires an image of a face and determines, with an arbitrarily small probability of a false positive, whether the face is of a person who is authorized to enter the environment. The method employed may include acquiring a digital image for comparison to a reference image and identifying two or more groups of pixels in the acquired image. The pixel groups in the reference image that are the best match for the two or more pixels groups in the acquired image are selected. The relative locations of the selected pixel groups in the reference image and the two or more pixel groups in the acquired image are compared, and the probability that the relative locations occurred randomly is determined.
