1. A system comprising:
an eyewear device, including:
a frame;
a temple extending from a lateral side of the frame;
an image display to present an overlay image to a user of the eyewear device;
a camera connected to the frame or the temple to capture an initial image of a scene the user of the eyewear device is viewing from a first perspective, the scene including a face;
another camera connected to the frame, the temple, or another temple and positioned to capture another initial image of the scene including the face from another perspective;
a processor coupled to the eyewear device and connected to the camera and the other camera;
a memory accessible to the processor; and
programming in the memory, wherein execution of the programming by the processor configures the system to perform functions, including functions to:
capture, via the camera, the initial image of the scene including the face;
capture, via the other camera, the other initial image of the scene including the face;
identify the face in the initial image of the scene;
identify the face in the other initial image of the scene;
identify facial feature parameters of the face in the initial image corresponding to an apparent size of the face in the initial image;
identify the facial feature parameters of the face in the other initial image;
track positional information of the face with respect to the eyewear device by comparing the identified facial feature parameters in both the initial image and the other initial image to a model trained using a plurality of images including faces having facial features with known positional information;
generate the overlay image responsive to the tracked positional information; and
present the overlay image on the image display.
