摘要： A method of encoding an image by transforming a group of prediction units into a frequency domain. A prediction unit may be predicted by using prediction values of the prediction units in the group of prediction units, instead of pixels generated by encoding and then restoring the other prediction units in the group of prediction units. Thus, an encoding compression ratio may be increased as a result of grouping the prediction units.
