#49 | fixed | Mismatch in VSP horSplitFlag derivation between WD and HTM | tech | Tomohiro Ikai |
Description |
The sign of inequality is different between WD(">") and HTM("<"), it poses different results (please see the following detail). Because the mismatch was occured in the text editing phase and the HTM has been tested for some meeting cycles. I think WD fix might be appropriate. An example of WD fix is attached. // WD horSplitFlag = ( refDepPels[ xP0 ][ yP0 ] > refDepPels[ xP1 ][ yP1 ] ) = = ( refDepPels[ xP1 ][ yP0 ] > refDepPels[ xP0 ][ yP1] ) ) (H 296) – The variables nSubBlkW and nSubBlkH are modified as specified in the following: nSubBlkW = horSplitFlag ? 8 : 4 (H 297) nSubBlkH = horSplitFlag ? 4 : 8 (H 298) // HTM ULvsBR = refDepthTmp[0][x+offset[0]] < refDepthTmp[3][x+offset[3]]; URvsBL = refDepthTmp[0][x+offset[3]] < refDepthTmp[3][x+offset[0]]; if( ULvsBR ^ URvsBL ) { // 4x8 // Detail ------------------------------ WD HTM ------------------------------ > 1 0 == 0 0 < 0 1 ------------------------------ -------------------------------------- WD UR>BL UR==BL UR<BL ---------------------------------------- UL>BR 8x4(1==1) 4x8(1==0)* 4x8(1==0) UL==BR 4x8(0==1)* 8x4(0==0) 8x4(0==0)* UL<BR 4x8(0==1) 8x4(0==0)* 8x4(0==0) ---------------------------------------- -------------------------------------- HTM UR>BL UR==BL UR<BL ---------------------------------------- UL>BR 8x4(0^0) 8x4(0^0)* 4x8(0^1) UL==BR 8x4(0^0)* 8x4(0^0) 4x8(0^1)* UL<BR 4x8(1^0) 4x8(1^0)* 8x4(1^1) ---------------------------------------- |
