[Resolution]:

-> IP

-> dimD remains as parameter



-> Check with Sinwook for the IP (mode 6 is mode 4 with some post-processing ?, is it generic or specific to SVA ?)

-> naming problem case 4 and case 6

    1. Tuesday


      Session

      MPEG-V

      9h to 11h

      Q1: 3rd edition?!

      Q2: review of ToC (e-nose, camera)


      Summary:

      Review of Automobile related types. There are 11 sensor types. An explanation of how the sensor data is used to compute the mille per gallon (an index of eco-friendly driving) should be added in the introductory part.


      AP: Issue WD for

      - Part 1 – TR (editor Jae-Joon): automobile scenarios, bubble effects, makeup

      - Part 2 – (editor same)

      - Part 3 – (same editors): bubble effect

      - Part 4 – (new editor Sang-Kyun Kim, co-editor Jae-Joon): makeup info

      - Part 5 – (same editors)

      - Part 6 – (same editors)
      Issue Request for 3rd editions of Parts 1 to 6. To review the requests Thursday morning.
      Bubble effect types reviewed to add the intensity, levels, and preferences.
      Makeup Info and Cosmetics:

      1. Create a PROTO called MakeUpSkinnedModel with three fields: SkinnedModel, MakeUpInfo and CosmeticsInfo; Create a proto called MakeUpInfo with fields: usage, toolType, name, brand, …; Create a proto for the CosmeticsInfo. An example software is needed to facilitate the design of the new protos.


      Dissemination:














      Session

      UD and AR

      11h to 12h

      Summary:

      Leonardo: The idea is that we should write a paper that describes our vision (MPEG path) in making augmented reality.

      Byoung-Dai Lee: introduction of the context awareness.

      The UD architecture was presented, it is not yet clear the role of each component.

      Recommendation: plan a joint meeting Thursday to continue the discussion.


      Session

      CDVS and AR

      12h to 13h

      Summary: presentation of the current ReferenceSignal. Presentation of the CDVS requirements. Local vs global descriptors.

      Recommendation: update the ReferenceSignal to include the descriptors. The CDVS should be represented in MP4 file format. For AR, how the distance between two descriptors is computed should be standardized.

      It may be interesting that once an object is detected in a frame, to try to find on the following frames the same object first. CD will be ready at the next meeting.

      Issue a Core Experiment that is defining the Proto including the CDVS.



      Session

      AR

      14h to 18h

      Summary: Proposal of the MPEGVWindSensorType (to be changed in MPEGVLocatedWindSensorType), similar for MPEGVLocatedLightSensorType.

      Recommendation: Create an application exemplifying the usage of these two DDF.



      m28340

      Proposed modifications for MAP related protos

      Not discussed yet



      Traian Lavric, Marius Preda

      Summary: MAP related nodes were updated.

      Recommendation: accepted.



      Session

      RMC (Break out Group)

      9h to 18h

      1. cross-check the ED_AD_EG

      [Resolution]:

      -> corrected the ED_AD_EG FU (some comments were added to the document, include it as it is) [done]
      2. cross-check the ED_BP

      [Resolution]:

      -> we need to update the BP to be more generic – it is compliant with the TFAN implementation

      -> The proposed generic FU (m28199) is not compliant with the SVA

      -> The proposed FU (m28219) is not generic and only covers a specific method used in SVA

      -> check if a subcase of this FU is still compliant with TFAN (even if it is do not include it as the ED_BP because it includes some coded specific parts).

      -> cross-check the design (during this week)
      3. Check IQ 1D (for mode = 1 – you need all 3 values to compute) – doesn't make sense in 1D

      [Resolution]:

      -> Removed mode 1 in 1D

      -> shifted modes (find solution for ehaviordence table – implement using LUT – in some decoders mode = X has a different meaning)


      4. Inverse Prediction (Md)

      -> Should dimD remain as parameter ?

      [Resolution]:

      -> dimD remains as parameter
      -> Check the newly added case 6 (predMode = 6) – it includes case 4 (ehavior differential prediction), is it the same ?

      [Resolution]:

      -> case 6 is the same as case 4: remove case 6
      -> Check the newly added case 7 (predMode = 7) – it includes case 4 (ehavior differential prediction), is it the same + some additional processing ?

      -> Check with Sinwook for the IP (mode 6 is mode 4 with some post-processing ?, is it generic or specific to SVA ?)

      -> naming problem case 4 and case 6

      -> check case 6 and define it as what it is (description + math )

      -> check if it is generic enough

      -> Investigate removing case 7 and design a SVA specific FU that applies post-processing to case 6 to implement case 7

      [Resolution]:

      -> still ongoing:

      -> Design 1 or 2 new Fus that implement the reordering and id necessary the post-processing in conjoint with IP to implement case 6 (design during this week)

      -> corss-check of the new design (during this week)

      -> implementation and corrections during editoral period ?
      5. Add section in CD: Context Modeling

      -> for the known decoders (MPEG/Part) provide the Fus

      [Resolution]:

      -> Fus are designed, to be included

      -> provide 2 examples implemented using generic Fus (LUTs+Mngt)

      [Resolution]:

      -> Christian to provide the TFAN context modeling implementation using LUTs

      -> Seungto provide the SVA context modeling implementation using LUTs


      6. Granular IB

      -> check for EG and BP (mine) – also check LUTs – TFAN specific, change the name

      [Resolution]:

      -> will be done during this week


      -> IB Connectivity

      -> change name to Granular_InverseBinarization_XXX_SVA

      -> check DEMUX selection – there seems to be a mistake (+investigate using the extractSegmentData FU)

      [Resolution]:

      -> another granular IB_nType was proposed in the BoG but not checked

      -> if there is time, design the correct Granular IB Connectivity FU and discuss it during this meeting

      -> include it in TuC
      -> IB Coordinates

      -> Check description part (connectivity)

      -> check BP & EG

      -> naming problem (SVA)

      [Resolution]:

      -> update description and naming [ Cui Li ]

      -> update BP & EG [ Seung ]

      -> if there is time, discuss it during this meeting

      -> include it in TuC

      7. ExtractMask SC3DMC

      [Resolution]:

      -> re-check and include in CD


      8. Study the difference between Mgnt_ExtractSegment and Mgnt_ExtractBytes

      -> does it have the same ehavior as ExtractSegment ?

      [Resolution]:

      -> still ongoing, answer [ Seung ]


      9. ExtractFaceDirection

      -> naming problem

      [Resolution]:

      -> rename to ExtractFaceDirection_sVA, SVA specific [ Seung ]


      10. PostP (Post Processing)

      [Resolution]:

      -> not ok, should include only simple math operations

      -> check if it is fully detachable in all the cases (SVA)


      11. Provider

      -> change the name

      [Resolution]:

      -> changed, include it in the CD


      12. check ED Fus ( codeBytes and codeBuffer port names, be consistent)

      [Resolution]:

      -> to be done during the editorial period
      13. HEVC:

      [Resolutions]:

      -> contribution discussed (low delay decoder mXXXX)

      -> Start WD with the initial set of Fus that are already defined

      -> Continue the work on the latest HM10.0
      14. RVC based Energy Efficient Decoder

      [Resolution]:

      -> informal contribution to report the the RMC group (also presented in Green MPEG)
      RGC+RVC:

      -> CALL Mickael about package naming in CD (during the editorial period)

      -> move the network definitions as part of annex (schematic, fnd)

      -> Mickael: if the interface, input tokens and output tokens are the same => compliant

      -> FSMs as informative (weight on RS)

      -> put all the Fus in the generic section, specific to specific section, context modeling as a new section

      -> parameters as table in annex
