It was reported that the proposed method was based on a paper issued over 20 years ago.
It was reported that the proposed used an in-loop processing and a neighboring context to improve visual quality.
It was confirmed that the two features could be a basic coding structure in the next version of ITM at least.
It was reported that the proposed method generated some parameters adaptively by using neighboring pixels. This process occurred in en/decoder side, which was influence on the increase of a decoder complexity.
[Recommendation]
Encouraged to try more filters to further improve the subjective quality and avoid complex operation such as inversing matrix.
