METHOD AND IMAGE-PROCESSING DEVICE FOR HOLE FILLING

The present invention relates to an image-processing device and a method of assigning pixel values to adjacent pixel locations in an image (705) having unassigned pixel values. The method comprises the steps of generating first propagation pixel values (730) and first propagation weights (735) for propagating the first propagation pixel values (730) along a first direction towards the adjacent pixel locations by: generating the first propagation pixel values (730) for propagation to the adjacent pixel locations in the first direction, the first propagation pixel values (730) being based at least on assigned pixel values in a first region adjacent to the unassigned pixel locations; generating first propagation weights (735) for the first propagation pixel values (730) to account for discontinuities in pixel values of assigned pixel values in a second region adjacent to the hole along the first direction, such that the occurrence of a discontinuity in said assigned pixel values along the first direction results in lower first propagation weights (735); and assigning pixel values to the adjacent pixel locations based at least in part on the first propagation pixel values (730) and first propagation weights (735). The invention further relates to a computer program and a computer program product comprising the program for implementing the method.
