Abstract:
An apparatus for decoding an image includes an entropy decoder that performs entropy decoding to generate quantized transformation coefficients of a transformation unit in a coding unit and an inverse transformer that inverse quantizes the quantized transformation coefficients to generate transformation coefficients of the transformation unit and inverse transforms the transformation coefficients to generate residual components of the transformation unit.
