Sensation is the process of stimulation of sense organs resulting in neural impulses to the brain, while perception is the brain's interpretation of sensory information. Perception involves organizing, interpreting, and understanding sensory stimuli. There are two types of depth cues that aid depth perception: monocular or pictorial cues that can be perceived with one eye, and binocular cues that require two eyes. Monocular cues include relative size, superposition, height in field, linear perspective, texture gradient, relative clarity, light and shadow, and motion parallax.
