AGE RESTORATION FILTER FOR REDUCING ARTIFACT IN COMP ESSED IMAGES
Joonki Paik · 1997
The main drawback of the BDCT based compresIn this paper we propose a fast adaptive image restoration filter using DCT-based block-classification for reducing block artifact in compressed images. More specifically, edge direction of each block is classified by sion techniques is, however, the block artifact which represents the artificial discontinuity between adjacent blocks, and results from the independent processing of the blocks without taking into account the between-block pixel correlations [2].
