JCTVC-B056 [K. Chono, K. Senzaki, H. Aoki, J. Tajime, Y. senda (NEC)] Performance report of modified conditional joint deblocking-debanding filter

This contribution presents a modified version of the conditional joint deblocking-debanding filter described in JCTVC-A104. The modified conditional joint deblocking-debanding filter integrates comfort noise injection into its filtering process and uses predetermined small pseudo noise which is generated by applying high-band-pass filter to random values drown from uniform distribution. The addition of the small pseudo noise to the deblock-filtered image masks banding-noise. Simulation results reportedly show that the modified version significantly reduces the banding-noise with a negligible impact on video coding efficiency. It is proposed that the modified conditional joint deblocking-debanding filter is studied in TE/CE on in-loop filter for Test Model.

Negligible effect on PSNR performance.

Two prior relevant contributions JVT-C056 and Q15-B-15.

Even without IBDI, negligible objective performance difference.

Plan further work as TE.
