METHOD AND APPARATUS FOR ENCODING AND DECODING IMAGE IN PIXEL DOMAIN

摘要

Provided are a method and apparatus for encoding and decoding an image. The method of encoding an image includes: generating a first residual block of a current block using intra prediction or inter prediction; loss encoding the first residual block in frequency domain; decoding the encoded first residual block and restoring a second residual block in pixel domain; and entropy coding the restored second residual block. Therefore, an image can be easily restored based on addition and reduction of pixel domain without complex inversion operations in the frequency domain in decoding the encoded image.
