Ledit rapprochement consiste : a) à générer un ensemble d'images filtrées de base, chaque image filtrée de base correspondant à l'image filtrée à l'aide d'une valeur respective du paramètre de filtrage; b) pour chaque pixel d'au moins un sous-ensemble de l'ensemble de pixels, à se rapprocher de la fonction de filtrage au moyen d'une fonction de rapprochement respective basée sur les images filtrées de base, cette fonction de rapprochement dépendant du paramètre de filtrage dans une plage prédéfinie du paramètre de filtrage. Ledit procédé consiste en outre, pour chaque pixel du sous-ensemble, à identifier ce pixel comme étant un point clé candidat si la fonction de rapprochement possède un extrême local représentant aussi un extrême global par rapport au paramètre de filtrage dans une sous-plage respective à l'intérieur de ladite plage prédéfinie. Pour chaque pixel identifié comme étant un point clé candidat, le procédé consiste en outre : c) à comparer la valeur adoptée par la fonction de rapprochement avec la valeur du paramètre de filtrage correspondant à l'extrême global du pixel aux valeurs adoptées par les fonctions de rapprochement des pixels adjacents dans l'image avec les valeurs des paramètres de filtrage des extrêmes globaux respectifs de ces pixels adjacents; et d) à sélectionner le pixel sur la base de cette comparaison.

Title: Object tracking in zoomed video
Inventor: WAGGONER CHARLES BENJAMIN FRANKLIN
IPC: G06F3/0484
Filed: 2015-03-12
Abstract: A user can select an object represented in video content in order to set a magnification level with respect to that object. A portion of the video frames containing a representation of the object is selected to maintain a presentation size of the representation corresponding to the magnification level. The selection provides for a "smart zoom" feature enabling an object of interest, such as a face of an actor, to be used in selecting an appropriate portion of each frame to magnify, such that the magnification results in a portion of the frame being selected that includes the one or more objects of interest to the user. Pre-generated tracking data can be provided for some objects, which can enable a user to select an object and then have predetermined portion selections and magnifications applied that can provide for a smoother user experience than for dynamically-determined data.
