Digital image processingDigital image processing is the use of a digital computer to process s through an algorithm. As a subcategory or field of digital signal processing, digital image processing has many advantages over . It allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and distortion during processing. Since images are defined over two dimensions (perhaps more) digital image processing may be modeled in the form of multidimensional systems.
Motion controllerIn video games and entertainment systems, a motion controller is a type of game controller that uses accelerometers or other sensors to track motion and provide input. Motion controllers using accelerometers are used as controllers for video games, which was made more popular since 2006 by the Wii Remote controller for Nintendo's Wii console, which uses accelerometers to detect its approximate orientation and acceleration, and serves an image sensor, so it can be used as a pointing device.
Robotiquethumb|upright=1.5|Nao, un robot humanoïde. thumb|upright=1.5|Des robots industriels au travail dans une usine. La robotique est l'ensemble des techniques permettant la conception et la réalisation de machines automatiques ou de robots. L'ATILF donne la définition suivante du robot : « il effectue, grâce à un système de commande automatique à base de microprocesseur, une tâche précise pour laquelle il a été conçu dans le domaine industriel, scientifique, militaire ou domestique ».
EvaluationIn common usage, evaluation is a systematic determination and assessment of a subject's merit, worth and significance, using criteria governed by a set of standards. It can assist an organization, program, design, project or any other intervention or initiative to assess any aim, realisable concept/proposal, or any alternative, to help in decision-making; or to ascertain the degree of achievement or value in regard to the aim and objectives and results of any such action that has been completed.
Gamme dynamiqueLa gamme dynamique, ou plage dynamique ou simplement dynamique est le rapport de la plus grande à la plus petite valeur d'une grandeur. Cette grandeur peut caractériser l'intensité d'un son ou d'une lumière. Elle est mesurée par une valeur logarithmique en base 10 (décibels) ou en base 2 (bits ou « diaphs »). En photographie, le terme décrit le rapport entre l'intensité lumineuse la plus élevée et l'intensité la plus faible qu'un appareil photographique peut capturer.
Aquatic locomotionAquatic locomotion or swimming is biologically propelled motion through a liquid medium. The simplest propulsive systems are composed of cilia and flagella. Swimming has evolved a number of times in a range of organisms including arthropods, fish, molluscs, amphibians, reptiles, birds, and mammals. Swimming evolved a number of times in unrelated lineages. Supposed jellyfish fossils occur in the Ediacaran, but the first free-swimming animals appear in the Early to Middle Cambrian.
