METHOD AND APPARATUS FOR IMAGE ENCODING/DECODING

摘要

Disclosed are a method and an apparatus for encoding and decoding an image. The method for decoding an image comprises the steps of: comparing the size of the current transform unit with the size of the smallest transform unit (STU); and decoding information indicating whether transformation is performed on the current transform unit and determining whether to perform inverse transformation on the current transform unit based on the decoded information indicating whether the transformation is performed, when the size of the current transform unit is equal to that of the STU.
