HEVC CU 级别的分析

接下来有关HEVC的文章都是HEVC学习系列的延续，但由于序号偏多，为方便起见，就不再单独编号，直接以讨论内容作为题目了。

 

要研究CU级的代码，少不了要接触到这么一个类TComDataCU。为了比较顺畅地看代码，对这个类的重要成员自然需要有比较好的认识才行，这就是本文的目的，给大家提供一个共同讨论类中私有成员含义与作用的平台。

 

class TComDataCU
{
private:
  
  // -------------------------------------------------------------------------------------------------------------------
  // class pointers
  // -------------------------------------------------------------------------------------------------------------------
  
  TComPic*      m_pcPic;              ///< picture class pointer
  TComSlice*    m_pcSlice;            ///< slice header pointer
  TComPattern*  m_pcPattern;          ///< neighbour access class pointer

  // CU description

  UInt          m_uiCUAddr;           ///< CU address in a slice
  UInt          m_uiAbsIdxInLCU;      ///< absolute address in a CU. It's Z scan order
  UInt          m_uiCUPelX;           ///< CU position in a pixel (X)
  UInt          m_uiCUPelY;           ///< CU position in a pixel (Y)
  UInt          m_uiNumPartition;     ///< total number of minimum partitions in a CU
  UChar*        m_puhWidth;           ///< array of widths
  UChar*        m_puhHeight;          ///< array of heights

  Int           m_unitSize;           ///< size of a "minimum partition"
