FILM GRAIN FOR STEREOSCOPIC OR MULTI-VIEW IMAGES

摘要

A method and an apparatus for applying film grain to stereoscopic or multi-view images or sequences of stereoscopic or multi-view images are described. After retrieving an image pair or a set of multi-view images a depth map for the image pair or the set of multi-view images and a confidence map for the depth map are obtained. Film grain is then applied to non-occluded areas of the images in accordance with depth values of the depth map and confidence values of the confidence map. Occluded areas of the images are processed separately by first deriving depth values for these areas and then applying film grain to these areas in accordance with the derived depth values.
