HEVC预测块(PU)模式划分显示

转自：http://blog.csdn.net/pc__wang/article/details/27225443#L316

1. PU模式划分显示效果图

2. HEVC decoder 代码修改

该程序是基于HM 11.0/3D-HTM的，废话不多说了，给出修改代码步骤。

2.1 PU划分数据结构体定义及宏定义

为了不改变源代码程序逻辑，我们所有修改的代码都放在自己定义的预处理命令宏定义中。

在TypeDef.h中，定义自己的条件编译预处理命令。

#define statistics_mode 1//用于统计输出块信息

snippet_file_0.h

在TypeDef.h中，定义保存PU划分坐标点结构体。

#if statistics_mode struct PtPair { unsigned int _pt1x; unsigned int _pt1y; unsigned int _pt2x; unsigned int _pt2y; unsigned char mode; }; #endif

2.2 PU划分及mode向量定义

为了保存各帧CU及mode最终划分结果，在TAppDecTop.h文件中定义如下代码：

class TAppDecTop : public TAppDecCfg { private: #if statistics_mode std::vector<PtPair> m_plistPt;//用于保存CU划分及mode结果 std::vector<int> flag;//用于保存每帧的mode数量 #endif

2.3 修改各函数头，将m_plistPt传递进去

在TAppDecTop.cpp文件中, 按照下面的方式替换源代码：

//原来的代码 bNewPicture = m_cTDecTop.decode(nalu, m_iSkipFrame, m_iPOCLastDisplay); //修改成如下代码 #if statistics_mode bNewPicture = m_cTDecTop.decode(nalu, m_iSkipFrame, m_iPOCLastDisplay,m_plistPt); #else bNewPicture = m_cTDecTop.decode(nalu, m_iSkipFrame, m_iPOCLastDisplay); #endif

snippet_file_0.cpp

编译程序，肯定会出错，因为没有修改相应的函数头。在TDecTop.cpp文件中，按照下面的方式修改decode函数头：

#if statistics_mode Bool TDecTop::decode(InputNALUnit& nalu, Int& iSkipFrame, Int& iPOCLastDisplay,std::vector<PtPair>& list) #else Bool TDecTop::decode(InputNALUnit& nalu, Int& iSkipFrame, Int& iPOCLastDisplay) #endif

来自CODE的代码片

snippet_file_0.cpp

在TDecTop.h中，也需要对应修改decode函数声明，按照以下方式修改该函数声明：

#if statistics_mode Bool TDecTop::decode(InputNALUnit& nalu, Int& iSkipFrame, Int& iPOCLastDisplay,std::vector<PtPair>& list); #else Bool decode(InputNALUnit& nalu, Int& iSkipFrame, Int& iPOCLastDisplay); #endif

snippet_file_0.h

接下来，将m_plistPt传递到xDecodeSlice函数中，将decode函数中的xDecodeSlice(nalu, iSkipFrame, iPOCLastDisplay)修改成xDecodeSlice(nalu, iSkipFrame, iPOCLastDisplay,list);即将m_plistPt传递到xDecodeSlice函数中。同样地，需要修改相应的函数头，在TDecTop.cpp文件中，修改对应的函数头，按照下面方式修改：

#if statistics_mode Bool TDecTop::xDecodeSlice(InputNALUnit &nalu, Int &iSkipFrame, Int iPOCLastDisplay,std::vector<PtPair>& list ) #else Bool TDecTop::xDecodeSlice(InputNALUnit &nalu, Int &iSkipFrame, Int iPOCLastDisplay ) #endif

来自CODE的代码片

snippet_file_0.cpp

在TDecTop.h中,按照下面方式替换DecodeSlice函数声明：

#if statistics_mode Bool TDecTop::xDecodeSlice(InputNALUnit &nalu, Int &iSkipFrame, Int iPOCLastDisplay,std::vector<PtPair>& list ); #else Bool xDecodeSlice(InputNALUnit &nalu, Int &iSkipFrame, Int iPOCLastDisplay); #endif

snippet_file_0.h

接下来，在xDecodeSlice函数中，将m_cGopDecoder.decompressSlice(nalu.m_Bitstream, pcPic);替换成如下代码：

// Decode a picture #if statistics_mode m_cGopDecoder.decompressSlice(nalu.m_Bitstream, pcPic,list); #else m_cGopDecoder.decompressSlice(nalu.m_Bitstream, pcPic); #endif

snippet_file_0.cpp

不要忘了，修改对应的函数头和声明，按照下面方式修改：

在TDecTop.cpp文件中，

#if statistics_mode Void TDecGop::decompressSlice(TComInputBitstream* pcBitstream, TComPic*& rpcPic, std::vector<PtPair>& list) #else Void TDecGop::decompressSlice(TComInputBitstream* pcBitstream, TComPic*& rpcPic) #endif

snippet_file_0.cpp

在TDecTop.h文件中，

#if statistics_mode Void TDecGop::decompressSlice(TComInputBitstream* pcBitstream, TComPic*& rpcPic, std::vector<PtPair>& list); #else Void decompressSlice(TComInputBitstream* pcBitstream, TComPic*& rpcPic ); #endif

来自CODE的代码片

snippet_file_0.h

在decompressSlice函数中，将m_pcSliceDecoder->decompressSlice( ppcSubstreams, rpcPic, m_pcSbacDecoder, m_pcSbacDecoders) 修改成如下代码：

#if statistics_mode m_pcSliceDecoder->decompressSlice( ppcSubstreams, rpcPic, m_pcSbacDecoder, m_pcSbacDecoders, list); #else m_pcSliceDecoder->decompressSlice( ppcSubstreams, rpcPic, m_pcSbacDecoder, m_pcSbacDecoders); #endif

来自CODE的代码片

snippet_file_0.h

接着，修改相应的函数头函数声明：

在TDecSlice.cpp文件中，

#if statistics_mode Void TDecSlice::decompressSlice(TComInputBitstream** ppcSubstreams, TComPic*& rpcPic, TDecSbac* pcSbacDecoder, TDecSbac* pcSbacDecoders, std::vector<PtPair>& list) #else Void TDecSlice::decompressSlice(TComInputBitstream** ppcSubstreams, TComPic*& rpcPic, TDecSbac* pcSbacDecoder, TDecSbac* pcSbacDecoders) #endif

来自CODE的代码片

snippet_file_0.h

在TDecSlice.h文件中，

#if statistics_mode Void TDecSlice::decompressSlice(TComInputBitstream** ppcSubstreams, TComPic*& rpcPic, TDecSbac* pcSbacDecoder, TDecSbac* pcSbacDecoders, std::vector<PtPair>& list); #else Void decompressSlice ( TComInputBitstream** ppcSubstreams, TComPic*& rpcPic, TDecSbac* pcSbacDecoder, TDecSbac* pcSbacDecoders ); #endif

来自CODE的代码片

snippet_file_0.h

接下来，将decompressSlice函数中的m_pcCuDecoder->decompressCU ( pcCU );修改成如下代码：

#if statistics_mode m_pcCuDecoder->decodeCU ( pcCU, uiIsLast, list); m_pcCuDecoder->decompressCU ( pcCU , list); #else m_pcCuDecoder->decodeCU ( pcCU, uiIsLast ); m_pcCuDecoder->decompressCU ( pcCU ); #endif

来自CODE的代码片

snippet_file_0.cpp

当然，也有修改相应的函数头和函数声明：

在TDecCu.cpp文件中，

#if statistics_mode Void TDecCu::decompressCU( TComDataCU* pcCU,std::vector<PtPair>& list ) #else Void TDecCu::decompressCU( TComDataCU* pcCU ) #endif { #if statistics_mode xDecompressCU( pcCU, 0, 0,list ); #else xDecompressCU( pcCU, 0, 0); #enif }

来自CODE的代码片

snippet_file_0.cpp

在TDecCu.h文件中，

/// reconstruct CU information #if statistics_mode Void decompressCU( TComDataCU* pcCU,std::vector<PtPair>& list ); #else Void decompressCU ( TComDataCU* pcCU ); #endif   #if statistics_mode Void xDecompressCU( TComDataCU* pcCU, UInt uiAbsPartIdx, UInt uiDepth,std::vector<PtPair>& list ); #else Void xDecompressCU ( TComDataCU* pcCU, UInt uiAbsPartIdx, UInt uiDepth ); #endif

来自CODE的代码片

snippet_file_0.cpp

2.4 保存CU划分和mode选择结果

在xDecompressCU函数中，保存每一帧的CU划分结果及mode结果，在if( ( ( uiDepth < pcCU->getDepth( uiAbsPartIdx ) ) && ( uiDepth < g_uiMaxCUDepth - g_uiAddCUDepth ) ) || bBoundary )结束后，添加如下代码保存结果：

//==================================================================================// //==================================模式大小统计====================================// //==================================================================================// #if statistics_mode struct PtPair tmp; tmp._pt1x=uiLPelX; tmp._pt1y=uiTPelY; tmp._pt2x=uiRPelX; tmp._pt2y=uiBPelY;tmp.mode=*pcCU->getPartitionSize(); list.push_back(tmp); #endif

来自CODE的代码片

snippet_file_0.h

接着，修改xDecompressCU函数中的xDecompressCU函数递归调用，

if(binSlice&&( uiLPelX < pcSlice->getSPS()->getPicWidthInLumaSamples() ) && ( uiTPelY < pcSlice->getSPS()->getPicHeightInLumaSamples() ) ) { #if statistics_mode xDecompressCU(pcCU, uiIdx, uiNextDepth,list ); #else xDecompressCU(pcCU, uiIdx, uiNextDepth); #endif }

snippet_file_0.cpp

到目前为止，数据保存完成。接下来，就是怎样把CU划分显示出来。

2.5 PU划分结果显示

在decode()函数中修改xFlushOutput和xWriteOutput函数调用，

#if statistics_mode xFlushOutput( pcListPic,m_plistPt,flag ); #else xFlushOutput( pcListPic); #endif   #if statistics_mode unsigned long temp=0; for(int i=0;i<flag.size();i++) { temp +=flag[i]; } if(flag.empty()) flag.push_back(m_plistPt.size());//保存每帧mode个数 else flag.push_back(m_plistPt.size()-temp);//保存每帧mode个数 xWriteOutput( pcListPic, nalu.m_temporalId,m_plistPt,flag ); #else xWriteOutput( pcListPic, nalu.m_temporalId); #endif   #if statistics_mode if(flag.empty()) flag.push_back(m_plistPt.size()); xFlushOutput( pcListPic,m_plistPt,flag ); #else xFlushOutput( pcListPic); #endif

来自CODE的代码片

snippet_file_0.cpp

接着，修改xFlushOutput和xWriteOutput函数头和声明，

//TAppDecTop.cpp中修改对应的函数头 #if statistics_mode Void TAppDecTop::xWriteOutput( TComList<TComPic*>* pcListPic, UInt tId,std::vector<PtPair>& list,std::vector<int>& flag) #else Void TAppDecTop::xWriteOutput( TComList<TComPic*>* pcListPic, UInt tId) #endif   #if statistics_mode Void TAppDecTop::xFlushOutput( TComList<TComPic*>* pcListPic,std::vector<PtPair>& list,std::vector<int>& flag ) #else Void TAppDecTop::xFlushOutput( TComList<TComPic*>* pcListPic ) #endif   //TAppDecTop.h中修改对应的函数声明 #if statistics_mode Void TAppDecTop::xWriteOutput( TComList<TComPic*>* pcListPic, UInt tId,std::vector<PtPair>& list,std::vector<int>& flag); Void TAppDecTop::xFlushOutput( TComList<TComPic*>* pcListPic,std::vector<PtPair>& list,std::vector<int>& flag ); #else Void xWriteOutput ( TComList<TComPic*>* pcListPic , UInt tId); ///< write YUV to file Void xFlushOutput ( TComList<TComPic*>* pcListPic ); ///< flush all remaining decoded pictures to file #endif

snippet_file_0.cpp

现在到了最后关头，也是最重要的一部分，贴出xWriteOutput和xFlushOutput函数全部代码，不想具体说了，对照代码修改吧！

#if statistics_mode Void TAppDecTop::xWriteOutput( TComList<TComPic*>* pcListPic, UInt tId,std::vector<PtPair>& list,std::vector<int>& flag) #else Void TAppDecTop::xWriteOutput( TComList<TComPic*>* pcListPic, UInt tId) #endif #endif { TComList<TComPic*>::iterator iterPic = pcListPic->begin(); Int not_displayed = 0;   while (iterPic != pcListPic->end()) { TComPic* pcPic = *(iterPic); #if H_MV if(pcPic->getOutputMark() && pcPic->getPOC() > m_pocLastDisplay[decIdx]) #else if(pcPic->getOutputMark() && pcPic->getPOC() > m_iPOCLastDisplay) #endif { not_displayed++; } iterPic++; } iterPic = pcListPic->begin();   while (iterPic != pcListPic->end()) { TComPic* pcPic = *(iterPic);       #if H_MV if ( pcPic->getOutputMark() && (not_displayed > pcPic->getNumReorderPics(tId) && pcPic->getPOC() > m_pocLastDisplay[decIdx])) #else if ( pcPic->getOutputMark() && (not_displayed > pcPic->getNumReorderPics(tId) && pcPic->getPOC() > m_iPOCLastDisplay)) #endif { // write to file not_displayed--;   #if statistics_mode TComPicYuv *p_dstyuv=new TComPicYuv; TComPicYuv *p_orgyuv=pcPic->getPicYuvRec(); p_dstyuv->create(p_orgyuv->getWidth(),p_orgyuv->getHeight(),1,1,0); p_orgyuv->copyToPic(p_dstyuv); Pel *pY=p_dstyuv->getLumaAddr(); UInt stride = p_dstyuv->getStride(); for(UInt index = 0; index < flag[0]; index++) { for(UInt y = list[index]._pt1y; y <= list[index]._pt2y; y++) { for(UInt x = list[index]._pt1x; x <= list[index]._pt2x; x++) { switch(list[index].mode) { case SIZE_2Nx2N: if(y == list[index]._pt1y ) pY[y*stride + x] = 0; if(x == list[index]._pt1x ) pY[y*stride + x] = 0; break; case SIZE_2NxN: if(y == list[index]._pt1y ) pY[y*stride + x] = 0; if(y == list[index]._pt1y+(list[index]._pt2y-list[index]._pt1y+1)/2) pY[y*stride + x] = 0; if(x == list[index]._pt1x ) pY[y*stride + x] = 0; break; case SIZE_Nx2N: if(y == list[index]._pt1y ) pY[y*stride + x] = 0; if(x == list[index]._pt1x+(list[index]._pt2x-list[index]._pt1x+1)/2) pY[y*stride + x] = 0; if(x == list[index]._pt1x ) pY[y*stride + x] = 0; break; case SIZE_NxN: if(y == list[index]._pt1y ) pY[y*stride + x] = 0; if(y == list[index]._pt1y+(list[index]._pt2y-list[index]._pt1y+1)/2) pY[y*stride + x] = 0; if(x == list[index]._pt1x+(list[index]._pt2x-list[index]._pt1x+1)/2) pY[y*stride + x] = 0; if(x == list[index]._pt1x ) pY[y*stride + x] = 0; break; case SIZE_2NxnU: if(y == list[index]._pt1y ) pY[y*stride + x] = 0; if(y == list[index]._pt1y+(list[index]._pt2y-list[index]._pt1y+1)/4) pY[y*stride + x] = 0; if(x == list[index]._pt1x ) pY[y*stride + x] = 0; break; case SIZE_2NxnD: if(y == list[index]._pt1y ) pY[y*stride + x] = 0; if(y == list[index]._pt1y+3*(list[index]._pt2y-list[index]._pt1y+1)/4) pY[y*stride + x] = 0; if(x == list[index]._pt1x ) pY[y*stride + x] = 0; break; case SIZE_nLx2N: if(y == list[index]._pt1y ) pY[y*stride + x] = 0; if(x == list[index]._pt1x+(list[index]._pt2x-list[index]._pt1x+1)/4) pY[y*stride + x] = 0; if(x == list[index]._pt1x ) pY[y*stride + x] = 0; break; case SIZE_nRx2N: if(y == list[index]._pt1y ) pY[y*stride + x] = 0; if(x == list[index]._pt1x+3*(list[index]._pt2x-list[index]._pt1x+1)/4) pY[y*stride + x] = 0; if(x == list[index]._pt1x ) pY[y*stride + x] = 0; break; default: break;   } } } } if(flag.size()>1) { list.erase(list.begin(),list.begin()+flag[0]); flag.erase(flag.begin()); } #endif   #if H_MV if ( m_pchReconFiles[decIdx] ) #else if ( m_pchReconFile ) #endif { const Window &conf = pcPic->getConformanceWindow(); const Window &defDisp = m_respectDefDispWindow ?

2.6 解码看结果

将先编码过后的文件，用解码器解码，就会看到最终结果。有的可能不知道怎样使用解码器，贴出命令行供参考

TAppDecoder -b 2Dmodes.bin -o 2Dmodes.yuv （TAppDecoder解码器应用程序，2Dmodes.bin编码器输出的压缩文件，2Dmodes.yuv 为重建文件名，2Dmodes.yuv 总的2Dmodes可以任意取名）。
