theories of visual processing

Theories of visual processing explain how our brains interpret what we see. One idea is the *bottom-up* approach, where visual information from our eyes is sent to the brain, and the brain figures out what objects are based on features like shape, color, and movement. Another is the *top-down* approach, where our prior knowledge, expectations, and experiences influence how we perceive visuals. Many models combine both, suggesting that our perception results from analyzing visual data and using mental context. These theories help us understand how we quickly recognize objects, scenes, and faces around us.
