Document Summary

The top and bottom are the same colour. Surroundings give information to create the illusion. Colours stay the same even when the surroundings change. Rely on 2 concepts to organise the image: figure-ground organization (cid:449)hat"s the o(cid:271)je(cid:272)t (cid:894)figure(cid:895) a(cid:374)d grou(cid:374)d (cid:894)(cid:271)a(cid:272)kgrou(cid:374)d(cid:895, grouping gestalt principles (the whole is different form the sum of its parts) Similarity, proximity, good continuation, closure, and simplicity. Optical flow when things move together we see them as a group. Interact together to interpret the world around us. Organizing inputs into objects, get full picture. May need one or both eyes to be able to see the object and evaluate the stimulus. Different nerves coming from the brain into the face. Accommodation of the eye ability to focus on nearby objects: far o(cid:271)je(cid:272)t = flat le(cid:374)s, does(cid:374)"t (cid:374)eed to a(cid:272)(cid:272)o(cid:373)(cid:373)odate, near object = curve lens, needs to change size to adjust for the distance, enhances clarity. Contraction and relaxation of the muscle, provides information about the object.
