methods, decoders, and programs are provided. all blocks of an image that has been encoded are decoded. at least one sample of at least one block of the image is filtered by, for each block being filtered: for each sample being filtered: selecting a plurality of neighboring samples. for at least one neighboring sample, a difference is calculated between the neighboring sample and the sample. a modifier value is obtained. a modifier sum is derived based on a sum of the modifier values for the neighboring samples. a correction value is determined based on a conditional addition of at least one shifted version of the modifier sum, each shift having a same number of shift steps in each correction value determination. a filtered sample is derived based on the sample and correction value. the filtered sample is stored. the block and filtered sample is output towards a decoder output.
