1. A computing device, comprising: a first camera; a second camera; at least one processor; and memory including instructions that, when executed by the at least one processor, cause the computing device to: capture a first image using the first camera and a second image using the second camera; identify an elliptical shape within the first image, the elliptical shape being identified based at least in part on one or more image gradients computed along a portion of the elliptical shape, the elliptical shape corresponding to predicted representation of a face of a user of the computing device; determine one or more disparity values associated with at least a first portion of the first image and at least a corresponding portion of the second image, the first portion and the corresponding portion each corresponding to the predicted representation of the face of the user; and determine a portion of the first image corresponding to the face of the user based at least in part upon analyzing the elliptical shape and the one or more disparity values.
