ABSTRACT:
A method of processing block-based image information including up sample filtering pixels located along boundaries of image blocks using a first filter strength and up sample filtering at least a portion of the pixels that are not located along boundaries of the image blocks using a second filter strength. The method may alternatively include up sample filtering pixels located along boundaries of image blocks and image sub-blocks using the first filter strength. An up sample filter system which includes a first up sample filter which filters pixels located along boundaries of the image blocks using a first filter strength and a second up sample filter which filters pixels that are not located along boundaries of the image blocks using a second filter strength.
