Title
(EN) AUTOMATICALLY DETECTING AND ISOLATING OBJECTS IN IMAGES
(FR) DÉTECTION ET ISOLEMENT AUTOMATIQUES D'OBJETS DANS DES IMAGES
Abstract
(EN)
Systems and methods for automatically detecting and isolating objects in images. An image containing at least one object of interest is segmented by a segmentation module, based on the class of object each pixel of the image depicts. A bounding module then determines coordinates of a predetermined shape that covers at least a portion of the at least one object of interest. An application module then applies a bounding box having those coordinates and having the predetermined shape to the original image. In some embodiments, the coordinates are determined based on a mask layer that is based on the object classes in the image. In other embodiments, the coordinates are determined based on the mask layer and on an edge mask layer. Some embodiments comprise at least one neural network. In some embodiments, the objects of interest are text objects.

L'invention concerne des systèmes et des procédés pour détecter et isoler automatiquement des objets dans des images. Une image contenant au moins un objet d'intérêt est segmentée par un module de segmentation, sur la base de la classe d'objet que chaque pixel de l'image représente. Un module de délimitation détermine ensuite des coordonnées d'une forme prédéterminée qui couvre au moins une partie du ou des objets d'intérêt. Un module d'application applique ensuite une boîte de délimitation ayant ces coordonnées et ayant la forme prédéterminée à l'image d'origine. Dans certains modes de réalisation, les coordonnées sont déterminées sur la base d'une couche de masque qui est basée sur les classes d'objets dans l'image. Dans d'autres modes de réalisation, les coordonnées sont déterminées sur la base de la couche de masque et d'une couche de masque de bord. Certains modes de réalisation comprennent au moins un réseau neuronal. Dans certains modes de réalisation, les objets d'intérêt sont des objets de texte.
