1. A computing device, comprising: at least one processor; a right camera having a first field of view; a left camera having a second field of view at least partially overlapping the first field of view; memory including instructions that, when executed by the at least one processor, cause the computing device to: capture right image data with the right camera; capture left image data with the left camera; detect, using a face detection algorithm, a first right representation of a first face and a second right representation of a second face in the right image data, the face detection algorithm returning a first right bounding box for the first right representation and a second right bounding box for the second right representation; detect, using the face detection algorithm, a first left representation of the first face and a second left representation of the second face in the left image data, the face detection algorithm returning a first left bounding box for the first face and a second left bounding box for the second face, wherein the first right representation and the first left representation form a first set of representations for the first face and the second left representation and the second right representation form a second set of representations for the second face; determine that the first set of representations satisfy a first selection criterion, the first selection criterion corresponds to a larger stereo disparity; determine that the first set of representations satisfy a second selection criterion, the second selection criterion corresponds to a larger average bounding box size; determine that the first set of representations satisfy a third selection criterion, the third selection criterion corresponds to a shorter average distance to center of a camera field of view; and select the first face as a primary face for a face tracking algorithm to track in subsequent images based on at least one of the first set of representations satisfying two or more of the first selection criterion, the second selection criterion, or the third selection criterion.
