JVET-K0334 CE2: Tests on long deblocking (CE2.2.1.4) [D. Rusanovskyy, J. Dong, M. Karczewicz (Qualcomm)]
JVET-K1035 Description of Core Experiment 15 (CE15): Palette mode [Y.-C. Sun, Y. H. Chao, X. Xu]
Discussion Tuesday morning Track B (JRO):
- Investigate the palette variant proposed in JVET-K0411 and HEVC-SCC palette mode
- Investigate interrelationship with CPR
- Study the complexity impact of the two palette variants and CPR (in coordination with CE8)
(Initial version presented Wednesday 1430 (GJS & JRO.)
Future meeting plans, expressions of thanks, and closing of the meeting
Future meeting plans were established according to the following guidelines:
- Meeting under ITU-T SG 16 auspices when it meets (starting meetings on the Tuesday or Wednesday of the first week and closing it on the Tuesday or Wednesday of the second week of the SG 16 meeting – a total of 6–7.5 meeting days), and
- Otherwise meeting under ISO/IEC JTC 1/SC 29/WG 11 auspices when it meets (starting meetings on the Wednesday or Thursday prior to such meetings and closing it on the last day of the WG 11 meeting – a total of 8.5 meeting days).
In cases where high workload is expected for a meeting, an earlier starting date may be defined.
Some specific future meeting plans (to be confirmed) were established as follows:
- Wed. 3 – Fri. 12 Oct. 2018, 12th meeting under WG 11 auspices in Macao, CN.
- Wed. 9 – Fri. 18 January 2019, 13th meeting under WG11 auspices in Marrakesh, MA.
- Tue. 19 – Wed. 27 March 2019, 14th meeting under ITU-T auspices in Geneva, CH.
- Wed. 3 – Fri. 12 July 2019, 15th meeting under WG11 auspices in Gothenburg, SE.
The agreed document deadline for the 12th JVET meeting was agreed to be Monday 24 September...
JVET-K0022 CE2: Summary Report on In-Loop Filters [L. Zhang, K. Andersson, C.-Y. Chen]
This contribution provides a summary report of Core Experiment 2 on in-loop filters. Five categories, including 1) bilateral filter, 2) deblocking filters, 3) sample adaptive offset (SAO) filter, 4) Adaptive Loop Filters (ALF), and 5) non-local filters are covered by this CE.
Test conditions are specified for each category. The corresponding coding performance of each coding tool under evaluated in CE2 are summarized in this contribution. In addition, answers to questions mentioned the CE plan and crosschecking results are also integrated in this contribution.
CE2.1: Bilateral Filter
Test# | Description | Document# |
2.1.1 | Same as BMS/JEM version | |
2.1.2 | Bilateral filter – spatial filter strength adjustment | |
2.1.3 | In-loop bilateral filter (also operated after block reconstruction, i.e. affecting subsequent intra prediction) |
Test# | # of filter taps | Sample difference calculation | Parallel friendly (each sample can be filtered independently from other samples) | Table Size |
2.1.1 | 5 | 1×1 | Y | 2778 bytes |
2.1.2 | 5 | 1×1 | Y | 2778 bytes |
2.1.3 | 5 | 1×1 for intra 3×3 for inter | Y | 30000 18bits |
