摘要
A method and apparatus for encoding an image is provided. The method and apparatus include quantizing and entropy encoding a second frequency coefficient matrix that is generated by performing a partial exchange of one or more values between rows and between columns of a first frequency coefficient matrix. A method and apparatus for decoding image data that is encoded by using the method and apparatus for encoding the image is also provided.
