METHOD AND APPARATUS FOR ENCODING AND DECODING IMAGE USING MODIFICATION OF RESIDUAL BLOCK |
摘要 |
Provided are a method and apparatus for encoding and decoding an image. In the encoding method, a residual block of a current block is transformed using a predicted block of the current block so as to increase the spatial correlation among residual values, and DCT is performed on the transformed residual block, thus improving the efficiency of transforming a block having a region that is difficult to precisely predict. |
