INTER PREDICTION METHOD AND APPARATUS USING ADJACENT PIXELS, AND IMAGE ENCODING / DECODING METHOD AND APPARATUS USING SAME

WIPO Patent Application WO/2011/037420

A2

The present invention relates to an inter-prediction method and apparatus, and to an image encoding method and apparatus using same. The inter prediction method of the present invention for prediction encoding is characterized by determination of a modified block based on a prediction block of the current block, and comprises the steps of: determining current motion vector by estimating the motion of the current block; generating a reference block directed by the current motion vector; calculating current block adjacent pixels using the reference block adjacent pixels and a motion compensation coefficient or an average compensation coefficient; and generating a modified reference block from said generated reference block based on the motion compensation coefficient or the average compensation coefficient. According to the present invention, the block which is to be encoded can be more accurately predicted by reducing the differences between the actual block and the predicted block, and compression efficiency can be improved.
