    摘要: A method and apparatus for encoding a video, and a method and apparatus for decoding a video, for increasing image compression efficiency by spatially transforming, scaling and frequency-transforming residual image data. The method of encoding an image includes spatially transforming a residual block through performing wavelet transformation or downsampling on the residual block to have a size that is equal to or smaller than a maximum size of a transformation unit when the size of the residual block is larger than the maximum size of the transformation unit, and transforming the spatially transformed residual block to a frequency domain.
