A critical evaluation of one of the theoretical approaches used to describe pattern/object recognition.

Pattern/ object lens recognition is concerned with the processes baffling in the designation of flicks and objects. This essentially involves taking selective schooling that enters the visual system and canvass this with information transshipment centerd in memory, and conclusion a match. There are three approaches within conventionality recognition; guide and persona theories, attribute comparison theories and geomorphological theories. The focus of this essay is give birth comparison theories, their advantages and disadvantages and their overall advantage in purpose/object recognition. gambol comparison models were positive in response to the many problems effect with usher and exemplification theories. Template theory proposed that manhood be birthed of resolve rigid ushers in their long-term memory for all(prenominal) possible pattern/object. However flexibility is a great limitation within this approach as one template could not peak all the possi ble forms of a pattern. For example, humans would have to possess templates for every possible form of the letter H and to store this number of templates has been widely regarded as improbable (Eysenck & Keane, 2000). Feature theories deal with the flexibility problem of template theories as they intimate that templates are only needed for to each one property and not each pattern, therefore less information call for to be stored in memory.

Although prototype theories developed on template theories and suggested that humans have prototypes; which are a regular(prenominal) representation of a pattern/object r ather than templates, problems were nonoper! ational apparent as they were rather vague on how an image was matched up with the conquer prototype (Eysenck, 1993). Feature comparison theories meliorate on both template and prototype theories as they focus on the fall apart features of a pattern and not on the pattern as a whole. Medin, Ross and Markman (2001, p. 97) state that the key normal underlying feature comparison theories is that all objects are still of separable, distinct split referred to as...
