Abstract— Face recognition is a biometric system used to verify or identify a person from a digital image. This involve extracting features of face and then recognize it, regardless of expression, lighting, illumination, transformations (translate, rotate and scale image), ageing and pose. The existing approaches are deblurring based, joint deblurring and recognition, deriving blur invariant features and direct approach, which uses convolution model for performing face recognition in the presence of blur. So these methods cannot handle non uniform blurring situations that frequently arise from rotations and tilts in hand held cameras. In this paper, face recognition is done, in the presence of space varying motion blur. We have taken the concept that the set of all images obtained by non-uniformly blurring a given image form a convex set. We develop an algorithm based on TSF (Transformation Spread Function) model. On each focused …show more content…
I. INTRODUCTION
Face recognition is a biometric approach that employs automated methods to recognize or verify the identity of a living person based on his/her physiological characteristics. In general, a biometric identification system makes use of either behavior patterns (such as voice, hand-writing, or key-stroke pattern) or physiological characteristics (such as an iris pattern, fingerprint, or face) to identify a person. For all other biometric system, we need the active participation of subject. But in the case of face recognition system, we require neither the knowledge nor the cooperation of the subject.
Face recognition is a type of pattern recognition of a person's face which is recorded in a database for future attempts to recognize a person's identity. Face recognition are used in wide range of applications like security control and video retrieving. Automatic face recognition involves three key steps. Face detection, feature extraction and face

Using Examples of Case Studies, Critically Evaluate the Contribution Cognitive Neuropsychology Has Made to the Understanding of Normal Cognitive Function.

...as it relates to processes of cognition such as; memory, perception, thinking, recognition and the human ability to solve problems, ( Jansari, 2010 p.60). Since the second half of the nineteenth century neurologist began studying brain damage in patients, more specifically their research has examined the effect of brain damage and its implication for normal cognitive functions. It has therefore being argued that in order to understand a working system, one must understand how it can fail, (Jansari, 2010 p. 59). This can refine and possibly constrain existing theories, as well as inspire the formulation of future concepts with regards to the structure of normal cognition. Evidence is based on case studies of individual brain damaged patients who show deficits in particular areas of the brain, from such studies researchers infer that different areas of the brain are highly specialized. Furthermore the development of more accurate techniques, aided by more effective research paradigms has increased our understanding of cognitive functions, in areas such as disassociation, plasticity, memory, localization and face processing, which would be explored later in the essay. Cognitive neuropsychology has however shown that there are limitations in understanding cognition where questions regarding methodology may arise, for instance studying single patient symptoms may pose problem for generalization. This essay would therefore provide an account of how neuropsychology has contributed to our...

Social Responsibility

...raucous. Harley-Davidson’s image itself took a big shot due to the Hells Angels. This was a motorcycle gang wishing to become notorious for "drug trafficking and other organized crime activities," who used only Harley-Davidson motorcycles. All of this combined to lead to a decline in demand and sales throughout the entire industry during the 1960’s. The industry was really helped out with the release of the Hollywood film Easy Rider in 1969. This film helped change the public’s perception of bikers and sparked an increase in motorcycle demand which has lasted to this day. The motorcycle industry offers products which can be viewed as luxuries or wants as opposed to necessities. When concerning Harley-Davidson, most motorcycle owners have purchased their bikes as a second vehicle, using them more during weekends and off-time instead of during the work week. This implies that the motorcycles serve for recreational purposes and thus are an item which can be expendable at times. This has hurt the industry recently with the slight recession the United States economy is facing. Another interesting thing to note about the motorcycle industry is the different appeal bikes carry in different global regions. In the United States for instance, Harley-Davidson has had much success because of the market trends and tastes people enjoy. Harley-Davidson has benefited from a U.S. market which enjoys casual and recreational riding. This isn’t necessarily the case overseas, as in Europe the trendy...

...A Brief Summary Of The Situation At Vidsoft Management Essay Since going public Vidsoft Technologies has witnessed rapid expansion and revenue growth. Its CEO, Keith Nash, has created and maintains a strong customer-responsive culture. To uphold levels of motivation employees are given a high degree of autonomy over their work. Teamwork is incentivized and promotions come quickly to those who fit the mold. Alaji Babatunde - in his third year of employment and already a senior manager - manages two product lines and eleven staff. Unable to allocate his time effectively, he contemplates introducing a new layer of management to the organization structure. Babatunde identifies one suitable candidate among his staff and settles to look outside the company for the second. With the consensus of James White, Babatunde offers a management position to Jennah Li, a conscientious and admired member of the group. Soon after, Alex Hsu, a young engineer and a direct report of Li, cites irreconcilable differences and requests to be transferred to the group without a manager. Li, concerned that Hsu’s transfer may be seen as a sign of weakness on her part, insists he continue to report to her. How can this situation be best resolved? Babatunde’s first challenge is to understand why the problem manifested itself in the first place. The second is to match his managerial approach to the situation without further negatively impacting the equilibrium of the group. The solution requires a combination...

The New Black Face

...“The New Black Face Movement” The New Black movement is encouraging youth of my generation to adopt an attitude of assimilation instead of enduring a fight to keeping our identity. History is important to people of all cultures it helps to guide you by knowing where you’ve come from and it lets you know when you’ve elevated your way of thinking by honoring your ancestors and what they have fought for. The new black movement is encouraging a growth stunting amongst black people which is not helping to create a more progressive race but is instead encouraging children to lose themselves. The new black face is the result of the African experience while in America, forcible assimilation has always been a part of our culture, but there is a new threat implemented by enticing the youth with the “New Black Movement.” The notion of the new negro was coined by Alain Locke meaning by race, was black, but would not live in the stereotypical confines of what being black meant. But affluent African Americans such as Raven Symone and Pharrell have taken this idea and morphed it into what can be seen as an abandonment of identification, according to Pharrell, you must stop identifying with the African American group altogether and the positive accolades of hard work will elevate your status with society. But this idea is simply furthers the crisis of identification within black children. In the 1940’s there was a doll study performed by The Clarks determined that the black children overwhelmingly...

Human and Machine Intelligence Essay

...Human and Machine Intelligence Essay I have been tasked with examining the root similarities and differences between human and machine intelligence. This is no small feat considering the copious amounts of scientific and philosophical information attributed to each, including fact, speculation, conviction, or otherwise. Defining intelligence alone has been historically subjected to great debate; add to that the hypotheticals of artificial intelligence and a whole new scale of complications become apparent. Through the course of this essay Team C will analyze and discuss a handful of key variables pertaining to biological (human or human-like) and mechanical intelligences, including their presumed natures and components, etc., and in the case of machines current achievements, ambitions, and the direction of development. With greater understanding of the elements of each, Team C can begin to compare and contrast the two with as much precision as possible, given the level of uncertainty. Artificial Intelligence (AI) has been a difficult goal to reach for scientists. Major milestones have been crossed on the road to true AI. According to Anthony Tongen, “In 1999, a group of scientists from Emory University and Georgia Tech made a calculator (called the “leechulator”) with neurons taken from leeches” (Tongen, 2003). This adaptation of biological components and mechanical material strikes major ground in the collective effort to reach true melding of flesh and machine. By 2010 Swedish...
