Recommended: Importance of facial recognition

Facial recognition is very important and it is fundamental to everyday life, humans are born to be attracted to faces and this provides us with useful information. Faces are seen as special as they provide information about people. Humans are very good at determining familiar faces and this is done through facial recognition. This essay will analyse the two cognitive models and how they can be applied to each case study. The strengths and weaknesses will be discussed as well as many examples will be included. Face Recognition is used in everyday life as people need to remember a face in their jobs or when meeting someone for the first time. Examples of practical applications are Mug shots searching, security monitoring and surveillance systems …show more content…

This model has units that are organised into pools which are involved in face recognition (Pike & Brace, 2012). The elements in each pool are facial recognition units (FRU) which includes memories. Semantic information units (SIUs) is the next pool and this is where relevant information is stored so that one will be able to recognise the person for example occupation and nationality (Pike & Brace, 2012). Person Identity Node (PINs) is the section which includes the recognition of the face and then the name. The last element is known as the Lexical output which can be defined as units that represent outputs as words or names (Pike & Brace, 2012). Each of these pools are linked to each other and make facial recognition …show more content…

Evidence of this is a man of 40 years old became prosopagnostic after he had an accident and now he cannot identify friends, family and even his wife. He is still able to recognise some objects but the main issue is that he is unable to recognise faces (Farah, Wilson, Drain & Tanaka, 1993). This was due to brain damage and his main impairment is with facial recognition. He suffered head injuries and although he cannot recognise certain people he is able to identity some words and pictures (Farah et al 1993). He suffered injuries on his temporal lobe which makes him unable to remember things that were previously important. The IAC model doesn’t relate to prosopagnosia and this is what the case is discussing and so it is evident that Bruce and Young’s model can be applied to this case

Figure 9.4 – Stream When the stream starts, OpenCV, which is running on the server, starts detecting and recognizing faces and displaying the results in a list that resides on the right sidebar. A green box appears, containing the information and the image of the recognized face. If the detected face is unrecognized, a red box appears, containing the face of the unknown individual. Figure 9.5 – Detecting & Recognizing Faces Right after an unrecognized face is caught, an email is sent as an alert for the security guards, containing the unrecognized face of the individual, alongside the date, the time and the IP Camera’s information.

, and forehead. The local feature that is mainly used here is wrinkle feature of some particular portions of the face like forehead region, eye corners regions, eyelids, mid of eyebrows. Using five distance values, six features namely feature 1 to feature 6 are calculated in the following way: Feature 1 = (left to right eye ball distance) / (eye to nose distance)

However, William Fay has shed some light on this second group that has me feeling more convicted rather than an “Atta boy”. I talk to the lost as most of us do with our contact with the secular world.

In John Perry’s The Third Night, Weirob argues that without her body, even if she maintains the same brain, she will not be herself. She uses the example of Julia and Mary Frances to try and persuade Miller and Cohen that because she has “never seen [her body, she has] no attachment to it” (Perry 48). If someone was walking down the street and saw his friend, that person would be recognized by his body and by his physical appearance. The same can be said if someone had to be identified in a police line up.

I 'm not an average teenager, social media and all of the technological stuff can be too intense for me. As a child seeing fingerprint scanners in movies amazed me, I never thought I 'd see that in real life, but technology has made it so phones, laptops, lockboxes.

Unconscious transference has been found to affect eyewitness recall. Unconscious transference refers to the misidentification of an innocent person as the perpetrator due to seeing them in another context e.g before or when the event occurred. This occurs because of the way our brain retrieves information. In order to recall an event we have to reconstruct information using nerve pathways that were associated together during the event.

For example is when the child becomes aggressive, their behaviour changed. They used to be sociable but now they are isolating themselves because they are depressed. The Teacher assistant will recognise this by the change of the behaviour of the child, to communicate with the child effectively, the teacher will use a non verbal expression like facial expression to show to the child that they care and also they will change their tone of voice into calm and lower tone because this affects how the child will respond to the teacher and will also make the child feel comfortable.

Face recognition technology [1] is the least intrusive and fastest biometric technology. It works with the most obvious individual identifier – the human face. Instead of requiring people to place their hand on a reader (a process not acceptable in some cultures as well as being a source of illness transfer) or precisely position their eye in front of a scanner, face recognition systems unobtrusively take pictures of people 's faces as they enter a defined area. There is no intrusion or delay, and in most cases the subjects are entirely unaware of the process. They do not feel "under surveillance" or that their privacy has been invaded.

A set of characteristics by which something is familiar is an identity. People are able to recognize a chair by its flat surface and the legs that support it, however, humans adapt to this identity. For instance, there may be only one leg, but that does not stop it from being identified as a chair. When talking about humans the basic idea of identity tends to become perplexing. This does not stop oneself from identifying various people.

That is why those who suffer from prosopagnosia are still able to recognize and distinguish everyday objects like a fork from a spoon. An idea proposed by Diamond and Carey states that in order to recognize objects we need first-order relational information. First-order relational information is information about the

The authentication of Biometrics (i.e. the real authentication) which is used for identification and controlling the access which can be applied in the computer science. It is can be used in groups to identify the individuals under the surveillance. Biometric identifiers are used to labels the characteristics which can be measurable, the distinctive, and to describe the individuals. Biometric identifiers are being often categorized as behavioral versus physiological characteristics. Physiological are related to define the characteristics and the structure of the body.

INTRODUCTION Now a day’s a facial recognition system is a computer application and it is used for automatically identifying or verifying a person . This is done by comparing selected facial features from the image and a facial database. Face Recognition System focuses on contactless man and machine interface. The human face plays an important role in our interaction and people’s identity.
