    摘要: Methods and apparatuses for encoding and decoding images are provided. The method of encoding an image includes: generating a reference frame by modifying a previously encoded frame; and encoding a current block of a current frame based on a group including the previously encoded frame and the reference frame, wherein in the encoding the current block, a reference to a first frame included in the group is considered to be the same as a reference to any other frame included in the group.

    摘要: Provided are a method and apparatus for encoding an image, which can variably encode a residual of a current block that is predicted with a skip mode according to prediction modes of neighboring blocks, and a method and apparatus for decoding the encoded image. When both the prediction mode of the current block and the prediction modes of the neighboring blocks are skip modes, since the method of encoding the image also encodes the residual of the current block that is predicted with the skip mode, more bits can be assigned to the current block with a high probability of acting as a reference block for other blocks.
