Authors: Chia-Ming Tsai MediaTek T.-D. Chuang MediaTek C.-W. Hsu MediaTek C.-Y. Chen MediaTek Y.-W. Huang MediaTek Shawmin Lei MediaTek
Abstract
This contribution proposes to add three long strong filter sets in addition to the HEVC strong filter set for deblocking. It is reported that the proposed long strong filtering leads to negligible changes in BD-rate and encoding time, and decoding time increase is 3% for VTM3.0 CTC and and for CTC with ALF off. It is asserted that the subjective quality at high QPs is improved because of the long strong filter sets.
