Title (EN) METHODS AND APPARATUSES FOR FOREGROUND, TOP-OF-THE-HEAD SEPARATION FROM BACKGROUND
(FR) PROCÉDÉS ET APPAREILS POUR UNE SÉPARATION D'AVANT-PLAN, À L'EXTRÉMITÉ SUPÉRIEURE DE LA TÊTE, ET D'ARRIÈRE-PLAN
Abstract: front page image
(EN)Foreground and background regions of a digital image of a scene are distinguished from each other automatically. Foreground objects are identified in a binary image map that distinguishes between foreground pixels and background pixels. From the foreground objects, a primary foreground object is identified. Within the identified primary foreground object, a head region of the primary foreground object is located. Within the head region, patterns of foreground pixels and background pixels that are indicative of a head crown region are identified. Within the head crown region, pixels identified as background pixels that actually show portions of the primary foreground object are converted to foreground pixels, thus improving the accuracy of the binary image map.
(FR)Selon l'invention, on distingue automatiquement les régions d'avant-plan des régions d'arrière-plan d'une image numérique. On identifie les objets d'avant-plan dans une carte d'image binaire qui fait la distinction entre des pixels d'avant-plan et des pixels d'arrière-plan. A partir des objets d'avant-plan, on identifie un objet d'avant-plan principal. Dans l'objet d'avant-plan principal identifié, on localise une région de tête de l'objet d'avant-plan primaire. Dans la région de tête, on identifie des configurations de pixels d'avant-plan et de pixels d'arrière-plan qui sont indicatives d'une région de couronne de tête. Dans la région de couronne de tête, on convertit les pixels identifiés en tant que pixels d'arrière-plan et présentant en fait des parties de l'objet d'avant-plan principal en pixels d'avant-plan, améliorant ainsi la précision de la carte d'image binaire.
