1. A computer-implemented method comprising: generating, by a camera of a mobile computing device, a first image of first and second objects; generating, by the camera of the mobile computing device and at a later time than the first image is taken, a second image of the first and second objects; determining, by the mobile computing device, (i) an amount of change in position exhibited by the first object between the first image and the second image, and (ii) an amount of change in position exhibited by the second object between the first image and the second image; classifying, by the mobile computing device, the first object as closer to the camera than the second object based at least on (i) the amount of change in position exhibited by the first object between the first image and the second image, and (ii) the amount of change in position exhibited by the second object between the first image and the second image; in response to classifying the first object as closer to the camera than the second object based at least on (i) the amount of change in position exhibited by the first object between the first image and the second image and (ii) the amount of change in position exhibited by the second object between the first image and the second image, determining, by the mobile computing device, information regarding the first object; and providing, by the mobile computing device, the information regarding the first object.
