Abstract
(EN)
An image processing method according to the present invention comprises the steps of: extracting a first two-dimensional feature point from a two-dimensional face image; on the basis of a geometric model of a standard face, deriving a three-dimensional feature point set including a first three-dimensional feature point corresponding to the first two-dimensional feature point; generating a three-dimensional face model including the three-dimensional feature point set; estimating an input pose of the two-dimensional face image to determine whether to update the three-dimensional feature point set; updating the three-dimensional feature point set by relocating the first three-dimensional feature point according to the first two-dimensional feature point, on the basis of the determination on whether to update the three-dimensional feature point set; and projecting the three-dimensional face model onto the two-dimensional face image. The present invention comprises a physical computer-readable recording medium in which a program for executing, in a computer, an image processing method is recorded.

Un procédé de traitement d'image selon la présente invention comprend les étapes consistant à : extraire un premier point caractéristique bidimensionnel d'une image de visage bidimensionnelle ; sur la base d'un modèle géométrique d'une face standard, dériver un ensemble de points caractéristiques tridimensionnels comprenant un premier point caractéristique tridimensionnel correspondant au premier point caractéristique bidimensionnel ; générer un modèle de visage tridimensionnel comprenant l'ensemble de points caractéristiques tridimensionnels ; estimer une pose d'entrée de l'image de visage bidimensionnelle pour déterminer s'il faut mettre à jour l'ensemble de points caractéristiques tridimensionnels ; mettre à jour l'ensemble de points caractéristiques tridimensionnels par la relocalisation du premier point caractéristique tridimensionnel selon le premier point caractéristique bidimensionnel, sur la base de la détermination quant à savoir s'il faut mettre à jour l'ensemble de points caractéristiques tridimensionnels ; et projeter le modèle de visage tridimensionnel sur l'image de visage bidimensionnelle. La présente invention comprend un support d'enregistrement physique lisible par ordinateur dans lequel est enregistré un programme pour exécuter, dans un ordinateur, un procédé de traitement d'image.
