Cognitive Psychology: Objects of recognition -
November 20th, 2011
3 Stages of Object Recognition:
1. Object is segmented into a set of basic subjobects. This reflects the output of the early visual processing.
2. Once the object has been segmented into basic subobjects, one can classify the category of each subobject. Bieberman argues that there are 36 basic categories of subobjects, or geons. Recognizing a geon involves recognizing the features that define it, where these features describe elements of its generation such as the shape of the object and the axis along which it is moved.

3. Having identified the pieces out of which the object is composed and their configuration, one recognizes the object as the pattern composed from these pieces (prototype)
