Law enforcementLaw enforcement is the activity of some members of government who act in an organized manner to enforce the law by discovering, deterring, rehabilitating, or punishing people who violate the rules and norms governing that society. The term encompasses police, courts, and corrections. These three components may operate independently of each other or collectively, through the use of record sharing and mutual cooperation. Throughout the world, law enforcement are also associated with protecting the public, life, property, and keeping the peace in society.
Law enforcement agencyA law enforcement agency (LEA) is any government agency responsible for the enforcement of the law. LEAs which have their ability to apply their powers restricted in some way are said to operate within a jurisdiction. LEAs will have some form of geographic restriction on their ability to apply their powers. The LEA might be able to apply its powers within a country, for example the United States' Bureau of Alcohol, Tobacco, Firearms and Explosives or its Drug Enforcement Administration; within a division of a country, for example the Australian state Queensland Police; or across a collection of countries, for example international organizations such as Interpol, or the European Union's Europol.
Law enforcement officerA law enforcement officer (LEO), or peace officer in North American English, is a public-sector or private-sector employee whose duties primarily involve the enforcement of laws, protecting life & property, keeping the peace, and other public safety related duties. Law enforcement officers are designated certain powers & authority by law to allow them to carry out their responsibilities. Modern legal codes use the term peace officer (or in some jurisdictions, law enforcement officer) to include every person vested by the legislating state with law enforcement authority.
Outline of law enforcementThe following outline is provided as an overview of and introduction to law enforcement: Law enforcement – subsystem of society that promotes adherence to the law by discovering and punishing persons who violate rules and norms governing that society. Although the term may encompass entities such as courts and prisons, it most frequently applies to those who directly engage in patrols or surveillance to dissuade and discover criminal activity, and those who investigate crimes and apprehend offenders.
Public securityPublic security or public safety is the prevention of and protection from events that could endanger the safety and security of the public from significant danger, injury, or property damage. It is often conducted by a state government to ensure the protection of citizens, persons in their territory, organizations, and institutions against threats to their well-being, survival, and prosperity.
Facial recognition systemA facial recognition system is a technology potentially capable of matching a human face from a or a video frame against a database of faces. Such a system is typically employed to authenticate users through ID verification services, and works by pinpointing and measuring facial features from a given image. Development began on similar systems in the 1960s, beginning as a form of computer application. Since their inception, facial recognition systems have seen wider uses in recent times on smartphones and in other forms of technology, such as robotics.
Facial expressionA facial expression is one or more motions or positions of the muscles beneath the skin of the face. According to one set of controversial theories, these movements convey the emotional state of an individual to observers. Facial expressions are a form of nonverbal communication. They are a primary means of conveying social information between humans, but they also occur in most other mammals and some other animal species. (For a discussion of the controversies on these claims, see Fridlund and Russell & Fernandez Dols.
Emotion recognitionEmotion recognition is the process of identifying human emotion. People vary widely in their accuracy at recognizing the emotions of others. Use of technology to help people with emotion recognition is a relatively nascent research area. Generally, the technology works best if it uses multiple modalities in context. To date, the most work has been conducted on automating the recognition of facial expressions from video, spoken expressions from audio, written expressions from text, and physiology as measured by wearables.
Affective computingAffective computing is the study and development of systems and devices that can recognize, interpret, process, and simulate human affects. It is an interdisciplinary field spanning computer science, psychology, and cognitive science. While some core ideas in the field may be traced as far back as to early philosophical inquiries into emotion, the more modern branch of computer science originated with Rosalind Picard's 1995 paper on affective computing and her book Affective Computing published by MIT Press.
Facial motion captureFacial motion capture is the process of electronically converting the movements of a person's face into a digital database using cameras or laser scanners. This database may then be used to produce computer graphics (CG), computer animation for movies, games, or real-time avatars. Because the motion of CG characters is derived from the movements of real people, it results in a more realistic and nuanced computer character animation than if the animation were created manually.
École Polytechnique Fédérale de LausanneThe École polytechnique fédérale de Lausanne (EPFL; English: Swiss Federal Institute of Technology in Lausanne; Eidgenössische Technische Hochschule Lausanne) is a public research university in Lausanne, Switzerland. Established in 1853, EPFL has placed itself as a university specializing in engineering and natural sciences. EPFL is part of the ETH Domain, which is directly dependent on the Federal Department of Economic Affairs, Education and Research.
