Title (EN) PROCESSING METHOD AND DEVICE WITH VIDEO TEMPORAL UP-CONVERSION
(FR) PROCEDE ET DISPOSITIF DE TRAITEMENT AVEC CONVERSION-ELEVATION DE FREQUENCE TEMPORELLE DANS DES SYSTEMES VIDEO
Abstract:
(EN) The present invention provides an improved method and device for visual enhancement of a digital image in video applications. In particular, the invention is concerned with a multi- modal scene analysis for face or people finding followed by the visual emphasis of one or more participants on the visual screen, or the visual emphasis of the person speaking among a group of participants to achieve an improved perceived quality and situational awareness during a video conference call. Said analysis is performed by means of a segmenting module (22) allowing to define at least a region of interest (ROI) and a region of no interest (RONI).
(FR) La présente invention concerne un procédé et un dispositif améliorés utilisés pour obtenir une amélioration visuelle d'une image numérique dans des applications vidéo. L'invention concerne notamment une analyse de scène multimodale consistant à rechercher un visage ou un personnage, cette analyse étant suivie de l'accentuation visuelle d'un ou plusieurs participants sur l'écran ou l'accentuation visuelle de l'intervenant dans un groupe de participants afin d'obtenir une meilleure qualité et de prendre mieux conscience de la situation au cours d'une visioconférence. Pour réaliser cette analyse, on utilise un module de segmentation (22) permettant de définir au moins une région d'intérêt et une région ne présentant pas d'intérêt.
