| 2General issues 2.1General discussion 2.1.1Reference Software
It is recalled that the source code of both decoder AND encoder should be provided as part of the Reference Software for all technologies to be adopted in MPEG standards. Moreover, not providing the complete software for a published technology shall conduct to the removal of the corresponding technical specification from the standard.
Currently almost all the AFX tools published in the second edition are supported by both encoder and decoder implementation. Only exception is the MeshGrid tool for the standalone decoder; however commitment was renewed by VUB, represented during this meeting by Leon Denis.
2.1.2Web site
OrangeLabs announced interrupting the maintenance of the group web-site. A call for volunteers is now issued. In the meantime 3DGC contributors are kindly asked to check the web-site and provide comments on the current version of the web-site.

CE Report on SC3DMC Ver 4.0
|
Authors
|
Seungwook Lee, Bonki Koo, Daiyong Kim, Kyoungsoo Son, Euee S. Jang
|
Summary
|
Objectives:
- speed up the decoding of QBCR, solution consists in reading more bits at the time
- add more parameter control on top of QBCR: delta prediction, entropy coding
- encode attributes: two proposals: one for normal and one for texture coordinates
The normal encoding includes two prediction methods: difference and XOR and two binarization (BP and AC)
The texture coordinates compression considers regular and not regular patches. The method is too complex for QBCR and SVA.
|
Resolution
|
Accept the proposed method for attributes encoding. Accept the delta prediction.

Optimized implementation of the TFAN encoder
|
Authors
|
Walid Hachicha, Khaled Mammou, Titus Zaharia
|
Summary
|
This contribution explains the dependency between encoder parameters and proposes to replace the exhaustive research for the optimal configuration with a near-optimal but faster approach. The contribution does not affect the bitstream syntax being related to the encoder.
|
Resolution
|
- accept the optimization as part of the RefSoft (Encoder side)
- add the formula for computing k in the Informative Annex on TFAN encoder

Summary

Editorial changes are proposed for TFAN.

- change the bitstream syntax for ensuring its byte-alignment
- introduce a detailed annex on the arithmetic decoder

CE Report on SC3DMC: FAE versus QBCR, QBCR BP and QBCR AC
|
Authors
|
Khaled Mamou, Faouzi Ghorbel
|
Summary
|
- the proposed extension of QBCR (called FAE) shows an average gain of 30-40% over QBCR, 10-20% over QBCR BP and equivalent compression results to QBCR AC
- FAE AC offers the best compression performances with an average gain (in terms of bitrates) of 10-30% w.r.t FAE
|
Resolution
|
- introduce the 7th order prediction in QBCR
- introduce mixed entropy encoding (AC+ExpGK) for QBCR and SVA
- evaluate the BPC and 4-byte binarization for QBCR
- maintain the fixed length binarization for QBCR in no prediction mode

1. Updates for the textual specifications (study text):
- introduce the different prediction modes for QBCR
- new header structure:
2. Updates for CE:
- add AC+ExpGK for QBCR and SVA
- compare AC+ExpGK with BPC for coordinates and attributes
- evaluate BPC over 4-bits binarization for QBCR

4.2.1Scene partitioning (14496-11 Amd.6)
SP is followed as a joint activity between Systems and 3DGC. The technology is integrated in Part 11. There was no joint meeting with Systems on this topic during this meeting.
SP activity on conformance and reference software continued.
4.3Maintenance 4.3.1FAMC Conformance and Reference Software
FNB reports on a problem related to FAMC reference software, namely the usage of little endian convention when writing the bitstream. This conducts to errors in parsing the FAMC bitstream when encapsulated in MP4. Resolution: issue a corrigendum on FAMC ref soft and conformance and ask the contributors to update the software and regenerate the bitstreams.
4.3.2AFX 3rd Edition
The document was updated during the week. Publication of the current version as FDIS (an editing period of 4 weeks is accepted).
