At the simplest level, recognition is based on superficial similarity, such as that between a tablespoon and a teaspoon. However, the similarity-based approach to recognition and categorization is incapable of accounting for fuzzy boundaries and different concepts of relative similarity (Robinson-Riegler, 191).
Other forms of similarity-based approaches such as that based on prototypical similarity and exemplars resolve only some of the deficiencies of the classical similarity-based understanding of human recognition (Robinson-Riegler, 200). The essentialist approach, for example, provides a much more comprehensive understanding of the process and roles of concepts and classifications in human recognition because it accounts for the learned context in which recognition occurs (Robinson-Riegler, 200-201).
The classical, prototype, and exemplar explanation for human recognition cannot adequately account for the functional and contextual difference...
They also found that there has been no adequate study on the effects of ageing and facial recognition. Despite these concerns, the report did acknowledge that biometric facial scanning was suitable for use when verifying photo documents, given that the preconditions, such as controlled ambient lighting, are met (cf. An investigation into the performance of facial recognition systems relative to their planned use in photo identification documents - BioP
127, 2005). An Eigenface representation (Carts-Power, pg. 127, 2005) created using primary "components" (Carts-Power, pg. 127, 2005) of the covariance matrix of a training set of facial images (Carts-Power, pg. 127, 2005). This method converts the facial data into eigenvectors projected into Eigenspace (a subspace), (Carts-Power, pg. 127, 2005) allowing copious "data compression because surprisingly few Eigenvector terms are needed to give a fair likeness of most faces. The method
Recognition Cognitive Process of Facial Recognition We see so many faces each day. How does the mind keep track of them all? Something that seems so simple is actually quite complex. There are a number of cognitive processes that help the mind recognize facial features in general but also familiar faces that represent known associates. The brain categorizes and codes facial features and relationships between those features that allow for a
Head Recognizing Faces There is a region in the brain, called the fusiform face area or FFA, which is vital in recognizing and distinguishing faces (Andrews et al., 2010). Brain scientists have been acquiring an understanding of the mechanisms, which distinguish faces. A baby's brain processes faces at four months as distinct objects. Faces tell a baby a lot of things, such as the person's identity, gender, race, emotion and truthfulness.
28 subjects comprised the normal control group. They were recruited through a newspaper ad and had no histories of Axis I psychiatric disorders. The subjects were shown images on a computer screen for 13, 26, 52, or 104 ms, sometimes upright and sometimes inverted, and were asked to indicate, by pressing one of two keys on a keyboard, whether the image of a face or a tree was located on
Criminal Identification Procedures The dawn of the twenty-first century has become the era of George Orwell's "1984." Technology that was found only in science fiction a few decades ago, is part of today's standards and procedures. The world today is filled with cameras that can film an individual wherever he goes, his cell phone signal can pinpoint his location, and even one glance can reveal his true identity (Shenk 2003). Iris-recognition technology,
