Question

Whatis the recognition-by-compopnets model of object recognition? Discuss evidence that supports this model.

(please give around a paragraph of description and please keep it simple and easy to follow)

Answer 1

Recognition by components or bottom up processing is a theory of perception proposed by Irving Biderman. Irvin suggestes that we are able to recognize the object by seperating them into geons (small components). Eg. If we are trying to see a mug, we would obviously take two things into mind a cylindrical shape and c shaped handle with it. If that object is without handle we may not percieve it as mug.

Biderman states that there are fewer than 36 geons which are combined to create object which we see in day to day life. This theory proposed that we look into two or more objects Edges -This helps us to maintain perception regardles of orientation and Concavities - Where two edges meet this help us to seperate between two or more geones.

Eg, if we see a plain grassland, we may think of it as plain grassland but if we see some swings, slides, jungle jims, merry go round we would obviously think of it as some park.

If we see a wooden plank, we may think of various objects of use or even waste - or if we see 4 wooden strong sticks, then obviously we would see it as table. We have recognized that plank more importantly the wooden sticks. Here if the table is made up, we see the edges and the concavities, which help us recognize
