METHOD FOR FILLING-IN MISSING REGIONS IN AN IMAGE OF A MULTIMEDIA CONTENT, CORRESPONDING COMPUTER PROGRAM PRODUCT AND APPARATUS

摘要

A method is proposed for filling-in missing regions in an image of a multimedia content. Such method comprises, for a block x comprising a patch x^a of known pixels and a patch x^u of unknown pixels:obtaining (300) a set {y_i} of N blocks of pixels;splitting (310) the set {y_i} for providing a set {y_i^a}, respectively {y_i^u}, of N patches referring to pixels in the set {y_i} having the same relative spatial positions as x^a, respectively x^u, in x;determining (320) a fill-in patch y_fill based on an optimization of an objective function subject to a boundary smoothness constraint taking into account at least one isophote vector estimated at position of at least one pixel p in x^a for insuring a smooth transition between the patches x^a and x^u;filling-in (330) missing regions in the image by associating the patch y_fill to the patch x^u.
