Size perception deals primarily with image size, but this is ambiguous because you need to account for distance. In order to know size, you must know distance. To begin with, it is important to know that depth is missing in the retina, and therefore we must use a variety of depth cues. These cues act like a guidance and give suggestions and clues at depth. In other words, they serve as the basis for perceptual inference. The cue approach focuses on information in the retinal image that correlates with depth in the scene, in which we learn a connection between the cue and perceived depth. This association then becomes automatic after repeated exposure. The cue approach includes monocular cues which are depth cues that are available even when the world is viewed only with one eye, binocular cues which rely on information from both eyes.
