Visual temporal attentionVisual temporal attention is a special case of visual attention that involves directing attention to specific instant of time. Similar to its spatial counterpart visual spatial attention, these attention modules have been widely implemented in video analytics in computer vision to provide enhanced performance and human interpretable explanation of deep learning models.
Calibration de caméraEn , l'opération de calibration de caméra revient à modéliser le processus de formation des s, c'est-à-dire trouver la relation entre les coordonnées spatiales d'un point de l'espace avec le point associé dans l'image prise par la caméra. Le terme calibration est un anglicisme dont l'équivalent français est étalonnage. On note aussi que le terme calibrage est couramment utilisé. Plusieurs modèles décrivant le processus de formation des images existent. Le plus simple est le modèle du sténopé ou modèle pin-hole dans la littérature anglo-saxonne.
Connected-component labelingConnected-component labeling (CCL), connected-component analysis (CCA), blob extraction, region labeling, blob discovery, or region extraction is an algorithmic application of graph theory, where subsets of connected components are uniquely labeled based on a given heuristic. Connected-component labeling is not to be confused with . Connected-component labeling is used in computer vision to detect connected regions in s, although s and data with higher dimensionality can also be processed.
Video content analysisVideo content analysis or video content analytics (VCA), also known as video analysis or video analytics (VA), is the capability of automatically analyzing video to detect and determine temporal and spatial events. This technical capability is used in a wide range of domains including entertainment, video retrieval and video browsing, health-care, retail, automotive, transport, home automation, flame and smoke detection, safety, and security. The algorithms can be implemented as software on general-purpose machines, or as hardware in specialized video processing units.
