Abstract:
1. A method of decoding an image, the method comprising: determining adjacent blocks adjacent to a current block having a motion vector; determining motion vector predictor candidates from among motion vectors of the determined adjacent blocks; determining a motion vector predictor of the current block from among the motion vector predictor candidates based on prediction mode information of the current block; and obtaining a motion vector of the current block based on the motion vector predictor and a differential vector obtained from a bitstream, wherein the image is hierarchically split from a plurality of maximum coding units, according to information about a maximum size of a coding unit, into coding units of coded depths according to depths, wherein a coding unit of a current depth is one of rectangular data units split from a coding unit of an upper depth, wherein the coding unit of the current depth is split into coding units of a lower depth, independently from neighboring coding units, and wherein coding units of a hierarchical structure comprise encoded coding units among the coding units split from a maximum coding unit.
