Method and device for intra prediction coding and decoding of images

摘要

A method and a device for intra prediction coding and decoding of an image in which the intra prediction according to a selected intra prediction mode based on a direction of an input image is performed arc provided. In the method and the device, an input block is frequency transformed, a direction of pixels in the input block is determined, and the intra prediction is performed according to an intra prediction mode that has the most similar direction to the determined direction of the pixels.
