Image encoding and decoding method and apparatus using motion compensation filtering

Image Number 5 for United States Patent #8045813.

Provided are an image encoding method and apparatus for encoding image data, in which compression efficiency is further improved by filtering motion-compensated image data, thereby reducing errors with respect to original image data, and an image decoding method and apparatus for decoding encoded image data. A filter is generated using previously decoded surrounding pixels of a current frame and surrounding pixels of a reference frame, and prediction data is then filtered using the generated filter. Therefore, it is possible to decrease a size of residual data to be encoded.
