    摘要： Provided are entropy encoding and decoding methods. The entropy encoding method includes receiving residual coefficients obtained by frequency converting a residual image, determining a first bit string about residual coefficients having nonzero levels from among the received residual coefficients, determining at least one lower bit, including a least significant bit of the first bit string, from the first bit string, and determining a second bit string obtained by bit-shifting the first bit string to the right by the number of lower bits.

    摘要： 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.

    摘要： 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.

    摘要： Methods and apparatuses for encoding and decoding a multi-view image are provided. The method of encoding the multi-view image can use a difference in views between pictures of the multi-view image, add an image area obtained from a picture at one view at a first time to a picture at another view at a second time, thereby generating a reference picture, and perform prediction encoding using the generated reference picture, thereby increasing prediction encoding efficiency.
