    摘要: A method and apparatus for encoding and decoding an image using a plurality of reference pictures. In an exemplary embodiment, the method of encoding an image comprises: generating information about transforms between a first picture and a second picture; generating a reference picture by transforming the second picture based on the generated information about transforms; predicting a current block of a current picture based on at least one of the reference picture and the first picture; and encoding the current block based on the predicting. Therefore, prediction encoding based on more accurate prediction is possible, thereby increasing a compression ratio of image encoding.

    摘要: Provided is are method and apparatus for video interprediction encoding/decoding. The method of video interprediction encoding/decoding includes extracting intraprediction-encoded/decoded blocks included in previously encoded/decoded pictures and predicting a current block from the extracted blocks. Thus, video encoding/decoding can be performed using both an intra (I) picture and correlation with adjacent pictures, thereby increasing the speed of video encoding/decoding.

    摘要: A deblocking filter used in a video encoder/decoder based on a multilayer is disclosed. The deblocking filtering method includes choosing a present block and its neighboring block on which a deblocking filtering will be performed, judging whether the present block and the neighboring block have been coded by the intra BL mode, choosing a deblocking filter strength according to the result of the judgment, and performing the deblocking filtering with respect to a boundary between the present block and the neighboring block and according to the deblocking filter strength.
