Abstract: The present invention relates to a method and apparatus for long-range facial and ocular acquisition. One embodiment of a system for acquiring an image of a subject's facial feature(s) includes a steerable telescope configured to acquire the image of the facial feature(s), a first computational imaging element configured to minimize the effect of defocus in the image of the facial feature(s), and a second computational imaging element configured to minimize the effects of motion blur. In one embodiment, the detecting, the acquiring, the minimizing the effect of the motion, and the minimizing the effect of the defocus are performed automatically without a human input.

Abstract: A method and apparatus are provided for determining or estimating the focal length of a camera based on a series of images captured by the camera. In one embodiment, a method for determining focal length includes obtaining a plurality of images of a three-dimensional scene from the camera, matching feature points across a subset of the images, deriving a projective reconstruction from the feature point matching, and finally recovering a metric reconstruction from the projective reconstruction in accordance with semidefinite programming. Once the metric reconstruction is recovered, the camera's intrinsic parameters, including focal length, can be estimated.
