1. A method for processing a digital picture, the digital picture comprising a plurality of pixels, the method comprising:
dividing the digital picture into a plurality of blocks, each block comprising a plurality of pixels; determining a type of block for each block; associating each block with a filtering mode of a plurality of different filtering modes according to the type determined for the block; and filtering each block using the associated filtering mode associated with the block, wherein the type of a block is determined based on a characteristic value of the block, and wherein the block is determined to be of an edge type if the characteristic value of the block is larger than a first threshold; the block is determined to be of a texture type if the characteristic value of the block is between the first threshold and a second threshold, the second threshold being smaller than the first threshold; and the block is determined to be of a homogeneous type if the characteristic value of the block is smaller than the second threshold.
