#23 closed defect (fixed)

Disparity vector derivation of VSP mode in depth coding

Reported by: hongbin.liu Owned by: tech
Priority: minor Component: HTM software
Version: HTM-6.1 Keywords: vsp
Cc: jct-3v@…, tech


In section H.8.5.4, NBDV is used to derive an initial disparity vector for both texture and depth. However, in HTM-6.1,NBDV is not called for depth, instead, (0, 0) is always used as an initial disparity vector.
As shown in the following codes, in function TComDataCU::getInterMergeCandidates, NBDV is called only when "bNoPdmMerge" is false, and "bNoPdmMerge" is fasle for texture but is true for depth.



#if FCO_DVP_REFINE_C0132_C0170

if( !getPic()->getDepthCoded() )


getDisMvpCandNBDV(uiPUIdx, uiAbsPartIdx, &cDisInfo , true

#if MERL_VSP_C0152

, true



A suggested revision is to change
if(!bNoPdmMerge | | ( getSlice()->getIsDepth() && getSlice()->getViewId() ) )
