Method and apparatus for encoding/decoding images using adaptive motion vector resolution
The present disclosure relates to a method and apparatus for improving the encoding efficiency by adaptively changing the resolution of the motion vector in the inter prediction encoding and inter prediction decoding of a video. The apparatus includes: a block identification unit for identifying a colocated block included in a reference picture as a block located at a position equal to a position of a current block; a moving block determiner for determining if the current block is a moving block, based on a motion vector of the colocated block; a motion vector determiner for determining a motion vector of the current block according to a result of the determining of if the current block is a moving block; and a resolution converter for converting a resolution of the motion vector of the colocated block.
