Abstract:
Methods and apparatuses for encoding and decoding an image are provided. The method of encoding an image includes: replacing a transformation coefficient having a low frequency component to be predicted from among transformation coefficients of a transformation block with a predetermined value; generating an incomplete residual block by inversely transforming the transformation block including the replaced transformation coefficient; and predicting the transformation coefficient having the low frequency component by using values of the incomplete residual block.
