METHOD AND APPARATUS FOR ENCODING AND DECODING AN IMAGE BY USING AN ADAPTIVE SEARCH RANGE DECISION FOR MOTION ESTIMATION

摘要

An encoding and decoding method and apparatus are disclosed. whereby, According to the disclosed method, in response to a current frame including a current block being a P frame, a motion vector and an intra-mode-to-inter mode ratio of a frame encoded and decoded previously to the current frame are analyzed in order to determine a temporal search range and a spatial search range of a reference frame.
