#68 | fixed | MV clipping bug in the sub-PU MPI default MV generation | tech | jicheng |
Description |
In HTM11, there is a MV clipping operation in the sub-PU MPI default MV generation, which is obviously a bug and should be removed to align with the WD. (This kind of bug was previously solved by NTT_BUG_FIX_TK54, but here it is introduced again by MPI_SUBPU_DEFAULT_MV_H0077_H0099_H0111_H0133.) In TComDataCU.cpp, line 4499, the following coded should be removed: clipMv( cMv ); |

#46 | fixed | Problem of all zero residual method in intra-picture | tech | jinheo |
Description |
I found a bug on A0087 document in HTM reference SW version 8.1 as well as 8.0. In the document, all zero residual method is only applied to inter-picture of depth. However, the method is only applied to intra-picture in both 3D-HTMv8.0 and v8.1. Line 2995 of TEncSearch.cpp (HTM8.0) is bTestZeroResi |= pcCU->getSlice()->getIsDepth() && pcCU->getSlice()->isIRAP(); It should be fixed to bTestZeroResi |= pcCU->getSlice()->getIsDepth() && !pcCU->getSlice()->isIRAP(); It affects the coding performance of AI and CTC. |

#56 | fixed | A bug caused by uncompressed InterDir in HTM10.0rc1 | tech | kaizhang |
Description |
A bug is found in HTM10.0rc1. Generally speaking, the original code tries to use InterDir to determine the prediction direction. However, InterDir is not compressed as MV and RefIdx. Thus a misalignment may occur. In some worse case, the codec may crash, although that does not happen in CTC. Attached please find a possible fix with macro HTM10RC1_FIX and the simulation results under CTC. There is a very minor difference (<0.001%) in the last column. At line 4746 in TComDataCU.cpp, it should be #if !HTM10RC1_FIX
#endif
#if HTM10RC1_FIX
#endif ... At line 4775 in TComDataCU.cpp, it should be #if !HTM10RC1_FIX
#endif
#if HTM10RC1_FIX
#endif Thank you! |
