JVET-M0471 CE11.1.6, CE11.1.7 and CE11.1.8: Joint proposals for long deblocking from Sony, Qualcomm, Sharp, Ericsson [M. Ikeda, T. Suzuki (Sony), D. Rusanovskyy, M. Karczewicz (Qualcomm), W. Zhu, K. Misra, P. Cowan, A. Segall (Sharp Labs of America), K. Andersson, J. Enhorn, Z. Zhang, R. Sjöberg (Ericsson)]
This contribution describes a parallel friendly long filter design for deblocking of large blocks common for CE11.1.6, CE11.1.7 and CE11.1.8. It further describes two variants of CTU line buffer reduction in CE11.1.7 and CE11.1.8 respectively. The CE tests are based on technologies that scored highly in subjective assessment carried out for CE11 before Macao meeting. It is asserted that all three tests give better subjective quality than the VTM-3.0 anchor.
The BD-Rate number for CE11.1.6 is Y/U/V reportedly shows 0.0%/-0.5%/-0.5% at AI, 0.0%/-0.8%/-0.8% at RA, 0.1%/-1.3% /-1.6% at LDB and 0.0%/-1.5%/-1.9% at LDP over VTM-3.0 with ALF switched on, respectively. When ALF is switched off, the BD-Rate results for Y/U/V reportedly shows 0.0%/-0.7%/-0.6 % at AI, 0.0%/-0.9%/ -0.9% at RA, 0.0%/-1.1%/-1.7% at LDB and 0.0%/-1.8%/-1.9% at LDP, respectively.
The BD-Rate number for CE11.1.7 is Y/U/V reportedly shows 0.0%/-0.5%/-0.5% at AI, 0.0%/-0.8%/-0.8% at RA, 0.1%/-1.4% /-1.5% at LDB and 0.0%/-1.5%/-1.9% at LDP over VTM-3.0 with ALF switched on, respectively. When ALF is switched off, the BD-Rate results for Y/U/V reportedly shows 0.0%/-0.7%/-0.6 % at AI, 0.0%/-0.9%/ -0.9% at RA, 0.0%/-1.3%/-1.6% at LDB and -0.1%/-1.9%/-2.0% at LDP, respectively.
The BD-Rate number for CE11.1.8 is Y/U/V reportedly shows 0.0%/-0.4%/-0.4% at AI, 0.0%/-0.7%/-0.7% at RA, 0.1%/-1.2% /-1.4% at LDB and 0.0%/-1.2%/-1.6% at LDP over VTM-3.0 with ALF switched on, respectively. When ALF is switched off, the BD-Rate results for Y/U/V reportedly shows 0.0%/-0.6%/-0.5 % at AI, 0.0%/-0.8%/ -0.8% at RA, 0.1%/-1.1%/-1.5% at LDB and 0.0%/-1.6%/-1.7% at LDP, respectively.
