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.

1. A method of decoding an image, the method comprising:
entropy decoding received bitstream, performing inverse quantization and inverse transformation of a residual, and restoring the residual; generating a prediction unit using prediction unit information and a motion parameter; extracting encoded filter information having at least one of a filter index and a filter coefficient; and restoring an image by adding a residual to the prediction unit wherein a coding unit CU has a recursive tree structure.
