Abstract:
An intraprediction method which improves compression efficiency using the symmetry of a video in the intraprediction of the video and a video encoding and decoding method and apparatus using the intraprediction method. The intraprediction method includes performing intraprediction by predicting a first region to be encoded in a video based on axial symmetry of a second region of the video with respect to a predetermined axis.
