摘要： A method of decoding an image includes the steps of restoring a residual value by performing inverse quantization and inverse transform on the residual value by entropy decoding a received bit stream, generating a prediction unit by performing intra prediction selectively using one of a plurality of prediction modes on a prediction unit split by conducting at least one of asymmetric partitioning and geometrical partitioning, and restoring an image by adding the residual value to the prediction unit. It may be possible to enhance encoding efficiency of high-resolution images having a resolution of HD or higher by performing intra prediction on the asymmetric partitioning and/or geometrical partitioning.

摘要： The invention relates to methods and apparatuses 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 methods and the apparatuses of the present invention involve dividing a macro-block having a pixel size of 32*32 or 64*64 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.

摘要： Disclosed is an adaptive intra-prediction encoding and decoding method. The adaptive intra-prediction encoding method comprises the following steps: providing a prediction unit to be encoded; determining the total number of prediction modes for intra-prediction in accordance with the size of the prediction unit; selecting a certain prediction mode on the basis of the displacement of a reference pixel among the determined total number of the prediction modes, and performing intra-prediction using the selected prediction mode; and transforming and quantizing the residual value, which is the difference between the prediction unit predicted by the intra-prediction and the current prediction unit, and entropy-encoding the transformed and quantized value. Thus, rate-distortion may be optimized and image quality and encoding speed may be improved.
