Title
(EN) METHOD AND DEVICE FOR TRAINING A NEURAL NETWORK TO SPECIFY LANDMARKS ON 2D AND 3D IMAGES

Abstract
(EN)
The present invention relates generally to a method, device and computer program product for training neural networks configured to generate specifications of landmarks related to two-dimensional or three-dimensional image data. The specification of landmarks is defined by three vectors with position, precision and presence values forming landmark specification vectors. The neural network extracts feature vector from input image data using convolutional neural network layers, decodes the feature vector, and outputs landmark specification vectors. The present invention further relates to a system of devices for specifying landmarks on images generated by neural networks running on the devices.

La présente invention concerne de manière générale un procédé, un dispositif et un produit programme d'ordinateur pour l'apprentissage de réseaux neuronaux configurés pour générer des spécifications de points de repère associés à des données d'images bidimensionnelles ou tridimensionnelles. La spécification des points de repère est définie par trois vecteurs avec des valeurs de position, de précision et de présence formant des vecteurs de spécification de points de repère. Le réseau neuronal extrait un vecteur de caractéristiques à partir de données d'image d'entrée à l'aide de couches de réseau neuronal convolutif, décode le vecteur de caractéristiques et délivre des vecteurs de spécification de points de repère. La présente invention concerne en outre un système de dispositifs permettant de spécifier des points de repère sur des images générées par des réseaux neuronaux s'exécutant sur les dispositifs.
