Video encoding/decoding method and apparatus

摘要

A method of encoding a video using motion compensated prediction includes determining an interpolation coefficient for making a prediction error between a to-be-encoded picture and a predictive picture minimize, the interpolation coefficient representing a pixel value change between the to-be-encoded picture and the encoded picture, interpolating a pixel in a position between adjacent pixels of the encoded picture using the interpolation coefficient to generate an interpolation picture, generating the predictive picture by subjecting the interpolation picture to motion compensated prediction, and encoding the prediction error between the to-be-encoded picture and the predictive picture.
