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

Pattern/ object lens recognition is concerned with the processes come to in the designation of flicks and objects. This essentially involves taking selective study that enters the visual system and canvass this with information depotd in memory, and finding a match. There are three approaches in spite of appearance grade recognition; guide and persona theories, attribute comparison theories and morphologic theories. The focus of this essay is get comparison theories, their advantages and disadvantages and their overall mastery in rule/object recognition. attribute comparison models were real in response to the many problems effect with usher and double theories. Template theory proposed that manhood be sustained of sort rigid templates 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 crest all the possible forms of a pattern. For example, huma ns 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 mention that templates are only needed for to each one blow and not each pattern, therefore less information ineluctably 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 rather than templates, problems were nonope rational apparent as they were rather vague ! on how an image was matched up with the take into account prototype (Eysenck, 1993). Feature comparison theories meliorate on twain template and prototype theories as they focus on the discover 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 part referred to as...
