Document Summary
When we perceive depth, we can locate objects in space. Our brains use two different types of cues to help perceive depth: binocular depth cues - based on input from both eyes together, monocular depth cues - based on input from one eye alone. Retina of each eye has slightly different view: the different views on the retina are binocular disparity, the brain has two different retinal images, even though they overlap. Flat images have no depth, yet we perceive depth in them: we perceive this 3-d two-dimensional image just with one eye. Leonardo da vinci first identified many of these cues: occlusion, height in field, relative size, familiar size, linear perspective, texture gradient. Cues in our brains and in the world allow us to perceive motion. Changes in illumination, together with object recognition processes enable you to perceive that an object is in motion. Two phenomena explain how visual system perceives motion: motion aftereffects, stroboscopic motion.
