    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.

    摘要： Provided are a method and apparatus for determining coding for coefficients of a residual block, an encoder and a decoder. The method includes generating a residual block by subtracting a motion-compensated prediction block from the current block; frequency-converting coefficients of the residual block into frequency coefficients; frequency-converting coefficients of the motion-compensated prediction block into frequency coefficients; and determining coding for each of the coefficients of the frequency-converted residual block based on the coefficients of the frequency-converted prediction block. Accordingly, the amount of information transferred to a decoder can be reduced by not coding some coefficients of the residual block.
