1. A method for applying film grain to stereoscopic or multi-view images or sequences of stereoscopic or multi-view images, the method comprising: retrieving an image pair or a set of multi-view images; retrieving a depth map for the image pair or the set of multi-view images; retrieving a confidence map for the depth map; applying film grain to non-occluded areas of the images in accordance with depth values of the depth map for areas of the depth map having a confidence equal to or higher than a specified threshold; applying either a weakened film grain to non-occluded areas of the images for areas of the depth map having a confidence lower than the specified threshold, or applying film grain to these areas in accordance with depth values manually specified by an operator, obtained by interpolation, or obtained from a temporal analysis of a sequence of stereoscopic or multi-view images; and applying film grain to occluded areas of the images in accordance with depth values manually specified by an operator, obtained by interpolation, or obtained from a temporal analysis of a sequence of stereoscopic or multi-view images.
