Since AC component prediction is one of linear interpolation techniques, it naturally generates distortions caused by over-undershoot in the case that the distribution of neighboring block average values is extremely large. In terms of threshold processing removing these distortions, the paper improves average prediction image filter based on AC component prediction.
