Over the last thirty years or so, face recognition is an active research area in computer vision and one of the most successful applications of image analysis and understanding. Different algorithms have been proposed by researchers for solving this problem and many of them are considered as the state of the art. Nowadays, the face recognition problem is not only important in the research area, but it is vital in the commercial applications. A general statement of the face recognition problem can be formulated as follows: Given still or video images of a scene, identify or verify one or more persons in the scene using a stored database of faces. Due to this definition well-known algorithms such as PCA, ICA, LDA, EBGM, Bayesian Framework, HMM, SVM and Boosting are proposed by Turk et al. [1], Bartlett et al. [2], Zhao et al. [3], Wiskott et al. [4], Moghaddam et al. [5], Nefian et al. [6], Heisele et al. [7], and Lu et al. [8].These algorithms have acceptable success on the test image databases. Nevertheless, utilizing these algorithms in the commercial applications is subject to som...
The Facial Recognition Lab was performed in order to determine whether or not the familiarity effect can be used to influence an individual’s memory. In the lab, ten Most Wanted faces were shown and the subject was asked to study them for an indefinite amount of time. Once they clicked “Next”, they were shown 20 faces in random order, ten of which were from the list they had just studied and ten were new faces. The subject was asked to determine which were new and which were Most Wanted. In theory this should be a relatively easy task, because the subject does not necessarily need to remember that a face was on the previous list, merely that they had seen it before. That it was familiar to them. Thus, on the second day they were shown 20 faces again. If the subject was randomly assigned into the control group, then they saw the Most Wanted faces mixed in with ten new faces. Otherwise they were assigned into the false memory group and were shown the exact same 20 faces they had seen the previous day. The subjects are given a “discrimination index” based on their level of accuracy. The hypothesis is that the control group will perform significantly better (i.e. have a higher discrimination index) than the members of the false memory group. This is because the control group still merely has to recognize a face. Granted they aren’t aware of which group they are in, but to the false memory group, all of the faces will have some degree of familiarity. They must go a step further and actually reconstruct which faces were on the Most Wanted list and which were not.
Biometrics is, “the automated use of physiological or behavioral characteristics to determine or verify identity (biometricgroup.com, 2014).”16 The purpose of the paper is to provide information about different forms of Biometrics. With the ever increasing threat of terrorism at home and abroad, biometrics is emerging as a way to increase security across the world. It is important to point out current issues dealing with Biometrics and how they relate to people that may one day have to use them.
The principles and theories of Social Psychology are important and useful in assessing behaviors in situations. These social psychological principles and their applications can be seen in fictional films which can also be attributed to everyday life. One such film that holds certain social psychological perspectives is Will Gluck’s 2010 production of Easy A. A film about high school student Olive Penderghast and how a sudden change in popularity and financial status, after an unintentional rumor about how she supposedly lost her virginity to a college guy spread through the entire her school. The film draws on the behavioral connections of pronounced hussy Olive Penderghast and her English class’s assigned reading of The Scarlet Letter. Easy A depicts how Olive’s choice to handle the rumor by modeling the harlot in her reading and embroidering an A on her wardrobe lead her to be preserved as one. The reactions of townspeople in the Scarlet Letter are similar to those of her high school class mates. Through such actions, reactions, and behaviors of the film is able to addresses numerous social psychological perspectives. Some of these social perspectives include the Actor-Observer Difference in Casual Attribution, Self-fulfilling prophecy and Operant Conditioning.
The term biometrics is commonly known as the field of development of statistical and mathematical methods applicable to data analysis problems in the biological sciences. Though, even more recently it has taken on a whole new definition. Biometrics is an amazing new topic referring to “the emerging field of technology devoted to the identification of individuals using biological traits, based on retinal or iris scanning, fingerprints, or face recognition”. Biometrics has already begun using applications that range from attendance tracking with a time clock to security checkpoints with a large volume of people. The growing field of biometrics has really been put on the map by two things, the technological advances made within the last 20 years, and the growing risk of security and terrorism among people all over the world. In this paper I will focus on: the growing field of biometrics, why it is important to our future, how the United States government has played a role in its development and use, the risks involved, the implications on public privacy, and further recommendations received from all over the science and technology field.
In many countries the used of surveillance videos have been growing intensively. As a consequence, a large number of crimes were successfully recorded by the surveillance videos. Therefore, the question of identification of the person on the recording media or digital images is sent to the forensic experts more frequently. However, this can be a formidable task especially when the recordings are in bad quality and enhanced footage have failed to reveal the face (identity) of the suspect. Most of this problem is caused by the resolution of the system, uncalibrated equipment and the lack of efficient and practical method to identify the criminal suspect through surveillance images.

Social psychology is a science that study social thinking (how we perceive ourselves and others, judgement we make and our attitudes); social influence (such as pressure to conform, group of people) and social relations such as aggression and helping (David G. Myers, 2008).
Biometrics is described as the use of human physical features to verify identity and has been in use since the beginning of recorded history. Only recently, biometrics has been used in today’s high-tech society for the prevention of identity theft. In this paper, we will be understanding biometrics, exploring the history of biometrics, examples of today’s current technology and where biometrics are expected to go in the future.
I’m going to start off by stating that facial recognition has some benefits to offer for both businesses and consumers. Up until the last couple of years, this technology has been generally used by law enforcement to stop known criminals and for border control, but since then companies have shown more interest in using it for commercial uses.

My paper is based on an article from the text’s web site (chapter 9) entitled “Lack of sleep ages body’s systems.” The basic claim of the article is that sleep deprivation has various harmful effects on the body. The reported effects include decreased ability to metabolize glucose (similar to what occurs in diabetes) and increased levels of cortisol (a stress hormone involved in memory and regulation of blood sugar levels). The article also briefly alludes (in the quote at the bottom of page 1) to unspecified changes in brain and immune functioning with sleep deprivation.
In my interview I had the pleasure of conversing with an individual that was not only an adult learner but now also operates as an adjunct professor for adult learners at a university. Some might not realize the parallels of adult learners and yet still there are vast differences that impact both. It was refreshing to find an individual that was able to succeed as a professional, a student and most recently a professor at the same time. My goal is to introduce you my amazing interviewee and paint a vivid picture of his journey, his growth and through his challenges along the way. Surprisingly this interaction was able to take a lot of excuses and reasons of why a person would be to busy to go back to school.
Psychology is the investigation of the mind and how it processes and directs our thoughts, actions and conceptions. However, in 1879 Wilhelm Wundt opened the first psychology laboratory at the University of Leipzig in Germany. Nevertheless, the origins of psychology go all the way back thousands of years starting with the early Greeks. This foundation is closely connected to biology and philosophy; and especially the subfields of physiology which is the study of the roles of living things and epistemology, which is the study of comprehension and how we understand what we have learned. The connection to physiology and epistemology is often viewed as psychology, which is the hybrid offspring of those two fields of investigation.
Public Safety Officials have been battling the difficult question of profiling for quite a while. The question is how do they know the suspected individual fit the category associated with an offense? While it has been proven that many profiling cases are somewhat directed to a racial profile, it can be proven that people, given the discretion, are able to identify explanations for a series of behavioral events by identifying what that behavior accredits to. This theory, identified by Frite Heider, “suggested that we have a tendency to give casual explanations for someone’s behavior, often by crediting either the situation or the person’s disposition,” called the attribution theory. Until recently, a study of the like was considered to be a branch of sociology and not a form of psychology. Social psychology essentially became the focus on the individual rather than the group as a whole. Many thoughtful ideas are collected in response to the studies of social psychology. Human cognition is understood to arise from interacting socially; highlighting the importance of socialization. We use social cognition to develop our explanations and our ideas on why a person’s behavior is/does what it is/does.
“The term -information security- means protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction” (United States Code, 2008). In order to ensure the identity of who is trying to access the information, the concept of “Biometric Technology” has been developed in the last years. This essay will start explaining this concept and the characteristics of its development through the time. Then, the essay will offer a brief explanation of biometric systems operation and a description of different biometric systems developed until now. Finally, this research analyzes the current and future applications and the issues that surround it.
For most of us, the human face is one of the most common visual stimuli experienced on a daily basis. Starting from birth, we begin to identify the faces of those around us, soon becoming an everyday occurrence not given much thought to. In the following pages, I will be discussing face perception and the cognitive functions behind it, prosopagnosia, and the question of whether faces are any different from other specialized object recognition.
