METHOD AND APPARATUS FOR ENCODING/DECODING HIGH RESOLUTION IMAGES

摘要

The invention relates to a method and apparatus for encoding/decoding high resolution images, which involve setting the size of the prediction unit to be encoded to an expanded macro-block size in accordance with the temporal frequency characteristics or spatial frequency characteristics among pictures to be encoded, and performing motion prediction, motion compensation, and transformation on the basis of a set prediction unit size. In addition, the method and the apparatus of the present invention involve dividing a macro-block having a pixel size of 32x32 or 64x64 into at least one partition on the basis of an edge, and performing encoding processes for each partition. Accordingly, encoding efficiency can be improved for high definition (HD) or higher resolution high-resolution images.
