Abstract: A method and apparatus for encoding and decoding multi-view images. The multi-view image encoding method selects a block corresponding to a current block from another picture having a view-point which is different from a view-point of a current picture to which the current block belongs, on the basis of a global disparity vector representing a global disparity between the current picture and the other picture; and encodes the current block on the basis of block information of a block from among the selected block and blocks adjacent to the selected block. Accordingly, multi-view images can be encoded in consideration of the individual differences between the appearances of objects as well as global disparities between view-points.

Abstract: Provided are methods and apparatuses for converting a lower bit-plane image, and methods and apparatuses for inverse-converting the lower bit-plane image, which increase the correlation of the lower bit-plane image. According to the method of converting a lower bit-plane image, pixels of the lower bit-plane image are sequentially added or subtracted so as to generate a converted lower bit-plane image. Accordingly, the lower bit-plane image has higher regularity, and thus the efficiency of image processing using the lower bit-plane image is improved.

The multi-view image encoding method selects a block corresponding to a current block from another picture having a view-point which is different from a view-point of a current picture to which the current block belongs, on the basis of a global disparity vector representing a global disparity between the current picture and the other picture; and encodes the current block on the basis of block information of a block from among the selected block and blocks adjacent to the selected block. Accordingly, multi-view images can be encoded in consideration of the individual differences between the appearances of objects as well as global disparities between view-points.

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.
