Abstract: Systems, methods, and computer-readable media are disclosed for determining a depth or reflectance of objects. Example methods may include causing, by a camera device, infrared illumination within a field of view of the camera device, wherein the field of view is at least partially illuminated at a first illuminance value, detecting a human face present in the field of view, determining, using the first illuminance value, a depth value of a portion of the human face, determining, using the depth value, a user account associated with a user having the human face, and causing presentation of information associated with the user at the camera device based at least in part on the user account.

Abstract: Systems, methods, and computer-readable media are disclosed for determining a depth or reflectance of objects. Example methods may include illuminating a scene within a field of view of a device at a first illuminance value, detecting a reflected illuminance value, and determining a first reflectance value for a first object in the scene. Example methods may include identifying the first object, determining an orientation of the first object, and determining an estimated distance between the device and the first object based at least in part on the first illuminance value, the reflected illuminance value, and the first reflectance value.
