(FR) SCULPTURE INTERACTIVE POUR EXPLORATION VOLUMETRIQUE ET EXTRACTION DE CARACTERISTIQUES
Abstract
(EN)
The present invention provides a system of extracting a visual feature from a dataset, comprising a storage means for storing said dataset; retrieval means for retrieving said dataset from said storage means; display means for displaying an image of said retrieval dataset; means for defining a block of voxels corresponding to a selected portion of said displayed dataset, said block containing said visual feature therein; means for removing from said block voxels not containing said visual feature, to generate a feature block; means for generating a mask from said feature block; and means for rendering said dataset using said mask. A method of extracting visual features is also provided.
(FR)
L'invention concerne un système d'extraction d'une caractéristique visuelle à partir d'un ensemble de données, comprenant un moyen de stockage permettant de stocker ledit ensemble de données; un moyen d'extraction pour extraire l'ensemble de données à partir du moyen de stockage; un écran pour afficher une image dudit ensemble de données d'extraction; un moyen permettant de définir un bloc de voxels correspondant à une partie choisie dudit ensemble de données affiché, ledit bloc contenant ladite caractéristique visuelle, pour créer un bloc de caractéristique; un moyen permettant de créer un masque à partir dudit bloc de caractéristique; et un moyen pour le rendu de l'ensemble de données à l'aide dudit masque. L'invention concerne en outre un procédé d'extraction de caractéristiques visuelles.
