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.
TrackingVideo tracking is the process of locating a moving object (or multiple objects) over time using a camera. It has a variety of uses, some of which are: human-computer interaction, security and surveillance, video communication and compression, augmented reality, traffic control, medical imaging and video editing. Video tracking can be a time-consuming process due to the amount of data that is contained in video. Adding further to the complexity is the possible need to use object recognition techniques for tracking, a challenging problem in its own right.
Film (cinéma)vignette|Alexandre Dovjenko en train de réaliser un film. Un film est une œuvre du cinéma ou de l'audiovisuel, qu'elle soit produite ou reproduite sur support argentique ou sur tout autre support existant (vidéo, numérique). Ce terme (qui vient de l'anglais film qui signifie « couche », « voile ») est employé par métonymie, en référence à la pellicule chargée dans un magasin de caméra argentique, destinée aux prises de vues cinématographiques.
Gant électroniquevignette|alt=Un gant de données|Un gant de données. Un gant électronique (aussi appelé gant numérique ou gant de réalité virtuelle, ou encore, plus rarement, gant de données) est un gant comportant des capteurs, qui permet à un utilisateur de saisir presque naturellement un objet virtuel et de le manipuler, en numérisant en temps réel les mouvements de la main. Il est utilisé pour l'interface homme-machine dans la réalité virtuelle. Remarque : un simple capteur de localisation peut en général suffire à la prise et à la manipulation d’un objet.
Virtual cinematographyVirtual cinematography is the set of cinematographic techniques performed in a computer graphics environment. It includes a wide variety of subjects like photographing real objects, often with stereo or multi-camera setup, for the purpose of recreating them as three-dimensional objects and algorithms for the automated creation of real and simulated camera angles. Virtual cinematography can be used to shoot scenes from otherwise impossible camera angles, create the photography of animated films, and manipulate the appearance of computer-generated effects.
Carte de disparitéIn 3D computer graphics and computer vision, a depth map is an or that contains information relating to the distance of the surfaces of scene objects from a viewpoint. The term is related (and may be analogous) to depth buffer, Z-buffer, Z-buffering, and Z-depth. The "Z" in these latter terms relates to a convention that the central axis of view of a camera is in the direction of the camera's Z axis, and not to the absolute Z axis of a scene.
