1. A method for processing a spatial region of a video image represented in a video signal, the method comprising:
receiving an input image in a video bitstream comprising luminance and chroma pixel values;
determining a luminance indicator of a spatial image region in the input image based on a plurality of luminance pixel values in the spatial image region, wherein the luminance indicator indicates that a specific partition corresponding to a specific range of luminance levels is utilized in the spatial image region;
determining one or more filtering parameters for a deblocking filter, wherein the filtering parameters depend on the luminance indicator in the spatial image region; and
applying the deblocking filter to the spatial image region to generate a filtered image region, wherein the deblocking filter with the same filtering parameters is applied to filter the plurality of luminance pixel values in the spatial image region to generate a plurality of filtered luminance pixel values in the filtered image.
