  • Publication number: 20120201474
    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.
