1. A computer-implemented method of selecting a video frame for facial recognition, comprising: under control of one or more computing systems configured with executable instructions, initiating a capture of video information on an electronic device; detecting at least one feature in the video information indicative of a person's head; in response to detecting the at least one feature, activating at least one infrared (IR) imaging mechanism of the electronic device operable to illuminate the person with at least one wavelength of IR light and detect IR light reflected back from the person; detecting features corresponding to the person's pupils in the reflected IR light; analyzing the detected features to determine at least one of an orientation, a measurement, or a level of focus of the detected features in the reflected IR light; selecting a current frame of video information when at least one of the orientation, measurement, or level of focus of the detected features meets a specified selection criterion; and performing facial recognition on the selected frame.
