Document Summary

Form perception: vision is our dominant sense, = process through which you manage to see the basic shape and size of an object, object recognition = process through which you identify what the object is. Why is object recognition crucial: applying your knowledge to the world (e. g. putting on shoes, leaning combining information bits collected on different occasions, interactions with the world. Beyond the information given: reversible figure perceiving images in different ways (e. g. the necker cube or the ambiguous figure). Recognition: some early considerations: some influences come directly from the stimulus itself the features that are in view; stimuli driven or bottom-up influences, other influences come from you, rather than the stimulus; knowledge driven or expectation driven. Features: perhaps instead of recognizing parts of an object (circle on top of stick. Word recognition: object recognition begins with detection of simple features; then separate mechanisms are needed to put the features together into a complete object.
