    摘要： Methods and apparatuses for encoding and decoding video are provided. The encoding method includes: performing motion estimation on a current block according to a first sub-pixel unit, and obtaining a motion vector in the first sub-pixel unit with respect to the current block; interpolating a reference picture indicated by the motion vector according to a second sub-pixel unit smaller than the first sub-pixel unit; using the interpolated reference picture, selecting a second sub-pixel in the second sub-pixel unit adjacent to a first sub-pixel in the first sub-pixel unit of the reference picture; selecting a corresponding region that has a smaller error with the current block, from among a first corresponding region of the reference picture and obtained with respect to the first sub-pixel, and a second corresponding region of the current block and obtained with respect to the selected second sub-pixel; and encoding information of the selected corresponding region.

    摘要： An image transforming method, an image transforming apparatus, an image inverse-transforming method, and an image inverse-transforming apparatus are provided. The image transforming method includes the operations of selecting a predetermined frequency area for performing a frequency transformation with respect to an M×N (where M and N are positive integers) input block, acquiring a truncated transform matrix by selecting elements to be used for a generation of transformation coefficients which correspond to the selected frequency area from among elements of an M×N transform matrix, and generating the transformation coefficients which correspond to the selected frequency area by performing the frequency transformation by applying the truncated transform matrix to the M×N input block.
