METHOD AND APPARATUS FOR ENCODING/DECODING IMAGE WITH REFERENCE TO A PLURALITY OF FRAMES

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.
