Abstract: A method of authenticating a user of a wearable electronic device includes emitting light into a dorsal side of a forearm near a wrist of the user; receiving, using a light field camera, remissions of the light from the dorsal side of the forearm near the wrist of the user; generating a light field image from the remissions of the light; performing a synthetic focusing operation on the light field image to construct at least one image of at least one layer of the forearm near the wrist; extracting a set of features from the at least one image; determining whether the set of features matches a reference set of features; and authenticating the user based on the matching. In some embodiments, the method may further include compensating for a tilt of the light field camera prior to or while performing the synthetic focusing operation.

Abstract: This disclosure pertains to operations, systems, and computer readable media to capture images of a scene using a camera array and process the captured images based on a viewer's point of view (POV) for immersive augmented reality, live display wall, head mounted display, video conferencing, and similar applications. In one implementation, the disclosed subject matter provides a complete view to a viewer by combining images captured by a camera array. In another implementation, the disclosed subject matter tracks the viewer's POV as he moves from one location to another and displays images in accordance with his varying POV. The change of the viewer's POV is inclusive of movements in the X, Y, and Z dimensions.
