Method and apparatus for coding/decoding image
The present disclosure provides an apparatus for decoding a video, the apparatus including at least: a bitstream decoder configured to extract information on a size of a transform unit and generate a quantized frequency transform block from a bitstream; an inverse quantization unit configured to reconstruct a frequency transform block by inversely quantizing the quantized frequency transform block; an inverse transformer configured to reconstruct a residual block by inversely transforming the frequency transform block, the inverse transformer selecting an inverse transform scheme among a plurality of inverse transform schemes in consideration of the size of the transform unit; a predictor configured to generate a predicted block in a prediction mode selected among an intra prediction mode and an inter prediction mode; and an adder configured to reconstruct a current block by adding a first pixel corresponding to the residual block and a second pixel corresponding to the predicted block.
