CA 2681342

A system and method for region classification of two-dimensional (2D) images for 2D-to-3D conversion of images to create stereoscopic images are provided. The system and method of the present disclosure provides for acquiring a two-dimensional (2D) image (202), identifying a region of the 2D image (204), extracting features from the region (206), classifying the extracted features of the region (208), selecting a conversion mode based on the classification of the identified region, converting the region into a 3D model (210) based on the selected conversion mode, and creating a complementary image by projecting (212) the 3D model onto an image plane different than an image plane of the 2D image (202). A learning component (22) optimizes the classification parameters to achieve minimum classification error of the region using a set of training images (24) and corresponding user annotations.

L'invention concerne un système et un procédé de classification de régions d'images bidimensionnelles (2D) pour conversion d'images 2D-3D afin de créer des images stéréoscopiques. Le système et le procédé de la présente invention prévoient l'acquisition d'une image bidimensionnelle 2D (202) ; l'identification d'une région de l'image 2D (204) ; l'extraction de caractéristiques de la région (206) ; la classification des caractéristiques extraites de la région (208) ; la sélection d'un mode de conversion basé sur la classification de la région identifiée ; la conversion de la zone en un modèle 3D (210) sur la base du mode de conversion sélectionné ; et la création d'une image complémentaire en projetant (212) le modèle 3D sur un plan d'image différent d'un plan d'image de l'image 2D (202). Un composant d'apprentissage (22) optimise les paramètres de classification pour atteindre une erreur de classification minimum de la région en utilisant un ensemble d'images de formation (24) et des annotations d'utilisateur correspondantes.
