摘要： A method for eliminating discontinuity of block boundaries of an image encoded in units of blocks and an apparatus thereof. A filter for eliminating discontinuity of block boundaries of an image encoded in units of blocks with a predetermined size includes: a vertical edge filtering unit which eliminates the discontinuity in the vertical direction of the blocks, by filtering sequentially in units of blocks; a determination unit which determines a start point of discontinuity filtering in the horizontal direction according to a filtering mode of a macroblock formed with the blocks; and a horizontal edge filtering unit. If the vertical direction discontinuity filtering of the blocks is finished to the filtering start point determined by the determination unit, discontinuity filtering in the horizontal direction of the blocks is sequentially performed for which the vertical direction discontinuity filtering is finished. Accordingly, time taken for filtering is reduced and unnecessary memory is not required.

摘要： A method of removing blocking artifacts from block-coded digital images and an image reproducing apparatus using the same remove blocking artifacts from a block-coded digital image. The method includes adjusting filtering offsets on a block-by-block basis using motion vector (MV) and quantization parameter (QP) values; and performing deblocking filtering to remove the blocking artifacts from a decoded digital image using the adjusted filtering offsets. Accordingly, since the filtering offsets may be adaptively adjusted on a block-by-block basis to fit image characteristics, the blocking artifacts may be efficiently removed, thus, improving image quality.

摘要： Provided is a moving picture decoding method and apparatus. The decoding method includes storing coding information on a certain block and neighboring blocks, deriving a filtering coefficient to filter a boundary between blocks and predicting a motion vector of a certain block, based on the stored information, and filtering the boundary between the certain block and the neighboring blocks based on the derived filtering coefficient. Accordingly, the number of the memories and the amount of routing resources needed are reduced.
