Document Summary
Summary: object recognition is hard, gestalt principles: (cid:498)the sum is more than the sum of the parts(cid:499) Inference: heuristic mechanisms: perceptual committees, bayesian inference, explanation for illusory contours, impossible figures, etc. Object recognition is hard: occlusion, unusual viewpoints, novel examples, many different examples, how to identify an object, finding edges. Perceptual organization: object boundaries are inferred, illusory contours. Probability of a x probability that o ever occurs when a is out there in the world. Probability of a when o is present = What vs. where/how pathways: the main visual areas of the macaque monkey cortex, a partial (cid:498)wiring(cid:499) diagram for the main visual areas of the brain. Object recognition: selectivity: areas of human visual cortex specialized for faces, laces, body parts, and motion. Special cases of faces: holistic processing: face inversion, prosopagnosia. If you decompose white light, you"d find that the white light is created by light of different wavelengths.
