Method of reducing blocking artifacts from block-coded digital images and image reproducing apparatus using the same |
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.
