Method and apparatus for encoding images and method and apparatus for decoding images |
摘要 |
An apparatus for decoding an image includes an encoding information extractor which extracts split information indicating whether to split a coding unit of an upper depth into coding units of deeper depths and skip information indicating whether a prediction mode of a current coding unit is a skip mode, from image data and a decoding unit which determines a split structure of a maximum coding unit, according to the split information so that the maximum coding unit is hierarchically split as a depth increases and determines whether the prediction mode of the current coding unit is the skip mode according to the skip information. |

1. A method of decoding an image, the method comprising:
extracting split information indicating whether to split a coding unit of an upper depth into coding units of deeper depths; determining a split structure of a maximum coding unit, according to the split information so that the maximum coding unit is hierarchically split as a depth increases; extracting skip information indicating whether a prediction mode of a current coding unit is a skip mode, from bitstream; when the skip information indicates that the prediction mode of the current coding unit is the skip mode, determining the current coding unit as one prediction unit of which the prediction mode is the skip mode; and when the skip information indicates that the prediction mode of the current coding unit is not the skip mode, obtaining one or more prediction units from the current coding unit. |
