Document Summary
First-order contour: region in retinal image where light intensity changes abruptly. Second-order contour (emergent contour or subjective contour): constructed by perceptual system from first-order that are present; intensity between contours is less than that of first-order. Inverse projection problem: different object sizes can project the same retinal image. Image-processing stages: object in space or 2d image, 2d retinal image of objects, detect contours (edges) [fundamental building blocks, group contours to form basic shapes (gestalt, recognize object. Ganzfeld effect: visual field with no abrupt luminance changes; no contours. Whiteout (snow blindness): lack of contour in retinal image, eye will focus on closer objects (myopia) Template matching model: input is compared to the stored representation (template) Structuralism: define individual components and how they fit together; william. Gestalt: consider all parts together; problem is that it doesn"t explain how; max. Gestalt laws: proximity, similarity, good continuation, common fate (variant of good continuation): objects moving in same direction viewed as collective whole, closure.
