IMAGE ENCODING/DECODING APPARATUS AND METHOD TO WHICH FILTER SELECTION BY PRECISE UNITS IS APPLIED

摘要

According to the present invention, an image encoding/decoding method involves selecting, for units which are more precise than picture units, interpolation filters to be used in a motion compensated inter prediction to calculate sub-pixel values, wherein said precise units include at least one of a slice unit and a partition unit. Thus, encoding precision may be improved in a high resolution image having high definition (HD) or greater resolution.
