Title
(EN) METHOD AND SYSTEM FOR PREDICTING DYNAMICAL FLOWS FROM CONTROL INPUTS AND LIMITED OBSERVATIONS
(FR) PROCÉDÉ ET SYSTÈME DE PRÉDICTION DE FLUX DYNAMIQUES À PARTIR D'ENTRÉES DE COMMANDE ET D'OBSERVATIONS LIMITÉES
Abstract
(EN)
Systems and methods for determining states of flow of objects in a scene. The methods and systems include measuring states of the flow at observed sample points of the scene, wherein the scene contains a set of sample points having subsets of observed and unobserved sample points. Store in a memory an operator specifying time-varying dynamics of training states of flow of the objects in the scene. Estimate, using the operator and the measured states at the subset of observed sample points, the states of the flow of the objects at the subset of unobserved sample points of the scene. Output the states of the flow at the set of unobserved sample points of the scene, so as to assist in a management of managing states of flow of objects in the scene.

L'invention concerne des systèmes et des procédés pour déterminer des états d'un flux d'objets dans une scène. Les procédés et les systèmes comprennent la mesure d'états du flux au niveau de points d'échantillonnage observés de la scène, la scène contenant un ensemble de points d'échantillonnage ayant des sous-ensembles de points d'échantillonnage observés et non observés ; le stockage, dans une mémoire, d'un opérateur spécifiant une dynamique temporellement variable d'états d'entraînement de flux des objets dans la scène ; l'estimation, à l'aide de l'opérateur et des états mesurés au niveau du sous-ensemble de points d'échantillonnage observés, des états du flux des objets au niveau du sous-ensemble de points d'échantillonnage non observés de la scène ; et la sortie des états du flux au niveau de l'ensemble de points d'échantillonnage non observés de la scène, de façon à aider à une gestion d'états de flux d'objets dans la scène.
