Apparatus and method for fast Intra Prediction Algorithm

摘要

The present invention relates to a high-speed inter picture prediction coding method. The present invention relates to an inter picture prediction coding method for dividing a coding unit (CTU) into a coding unit and a prediction unit in inter picture prediction coding of HEVC (High Efficiency Video Coding) It is possible to determine the inter picture prediction coding mode at an early stage or to divide the coding unit early under a certain condition by using the size information of the coding unit, the predictive coding mode information and the rate-distortion cost information, By skipping the additional computation process in a manner that decides to terminate the partitioning procedure early, the rate-distortion cost is calculated for every number of coding units and prediction unit partitioning structures and prediction coding modes in all cases, The conventional HEVC inter prediction coding method is improved so that the complexity of the calculation is effectively reduced and the high rate-distortion performance Speed inter-picture prediction coding method and apparatus therefor.
