Method and apparatus for inter prediction encoding/decoding using sub-pixel motion estimation

摘要

the present invention includes an image of the inter-prediction encoding , the decoding method and apparatus according to the present invention in accordance with image the inter-prediction coding method estimates the first motion vector of the first pixel unit in the reference picture using a current block and , with the pixels adjacent to the first reference block according to a first motion vector estimated by estimating the second motion vector determining a second reference block used for the inter-prediction of the current block , and based on the second reference block determined by encoding the current block , referred to estimate the motion vector than with the correct precision and accuracy at the same time is consumed for encoding a motion vector of high it is possible to reduce the number of bits can improve the compression rate of image encoding .
