Title
(EN) BIAS LIGHTING EFFECT GENERATION FOR VIDEOS
(FR) GÉNÉRATION D'EFFET D'ÉCLAIRAGE D'AMBIANCE POUR DES VIDÉOS
Abstract
(EN)
Systems and methods for generating a bias lighting effect are provided. A computer-implemented method can include obtaining a video comprising a plurality of video frames. For each of one or more video frames of the plurality of video frames, the method can include sampling an edge portion of the video frame. The edge portion can include a portion of the video frame adjacent to an edge of the video frame. The method can further include generating a bias lighting effect for the video frame. Generating the bias lighting effect can include inverting the edge portion across the edge and blurring the edge portion. The method can further include displaying the video frame concurrently with the bias lighting effect for the video frame. The bias lighting effect can be displayed adjacent to the edge of the video frame.

La présente invention concerne des systèmes et des procédés permettant de générer des effets d'éclairage d'ambiance. Un procédé mis en œuvre par ordinateur peut consister à obtenir une vidéo comprenant une pluralité de trames vidéo. Pour chacune d'une ou plusieurs trames vidéo de la pluralité de trames vidéo, le procédé peut consister à échantillonner une partie de bord de la trame vidéo. La partie de bord peut comprendre une partie de la trame vidéo adjacente à un bord de la trame vidéo. Le procédé peut en outre comprendre la génération d'un effet d'éclairage d'ambiance pour la trame vidéo. La génération de l'effet d'éclairage d'ambiance peut comprendre l'inversion de la partie de bord à travers le bord et le floutage de la partie de bord. Le procédé peut en outre consister à afficher la trame vidéo simultanément avec l'effet d'éclairage d'ambiance pour la trame vidéo. L'effet d'éclairage d'ambiance peut être affiché de manière adjacente au bord de la trame vidéo.
