黑线提取的问题。。我怎么也看不懂。。

原理是先求底部两行的中心，再作为后行的基础
              最底行对该行所有黑块重心初始化
         但是这段程序的算法我怎么也看不懂。。请指教，谢谢！
         for(k = 0;k < MAX_BLACK_NUM;k++)
               {
                  g_BlackPoint[k] = INIT_DATA;
              }
              j = 0;
              cnt = 0;
            while(j < (MAX_VIDEO_POINT - 2) && (cnt < MAX_BLACK_NUM))
            {
                  if(g_VideoImageData[MAX_VIDEO_LINE - 1][j] < MIDDLE)
                  {
                     l_BlackStartDot = j;
                     if( (g_VideoImageData[MAX_VIDEO_LINE - 1][l_BlackStartDot + 1] < MIDDLE) && (g_VideoImageData[MAX_VIDEO_LINE - 1][l_BlackStartDot + 2] < MIDDLE))
                     {
                        while((g_VideoImageData[MAX_VIDEO_LINE - 1][j + 2] < MIDDLE) && (j < (MAX_VIDEO_POINT - 2)))

                              g_BlackPoint[cnt] = l_BlackStartDot / 2 + (j + 1) / 2;  // 记录该黑块中心，最多5块
                              cnt ++;

                  }
