opencv 用cvPryMeanShiftFiltering做图像分割，想将分块后每个区域设置个标签 生成一个label的mat 怎么做

  刚好我写了类似的代，但是我用的是 pyrMeanShiftFiltering() 这个函数，可能会稍有些不同。我把我的整个函数放在下面，你自己看下：
  void meanShiftSegmentation(cv::Mat &firstImage, cv::Mat &secondImage, cv::Mat &overlapSegmentsResults)
  {
  int imageHeight = firstImage.rows;
  int imageWidth = firstImage.cols;
  
  cv::Mat firstResults;
  cv::pyrMeanShiftFiltering(firstImage, firstResults,10,10);
  cv::Mat secondResults;
  cv::pyrMeanShiftFiltering(secondImage, secondResults,10,10);
  
  cv::Mat mask(imageHeight+2, imageWidth+2, CV_8UC1, cv::Scalar(0));
  uchar* maskData = mask.data;
  RNG rng=theRNG();
  for (int i = 0 ; i < imageHeight ; i++)
  {
  for (int j = 0 ; j < imageWidth ; j++)
  {
  if (maskData[(i+1)*imageWidth + j+1] == 0)
  {
  Scalar newcolor(rng(255),rng(255),rng(255));
  floodFill(firstResults,mask,Point(j,i),newcolor,0,Scalar::all(1),Scalar::all(1));
  }
  }
  }
  mask.setTo(0);
  for (int i = 0 ; i < imageHeight ; i++)
  {
  for (int j = 0 ; j < imageWidth ; j++)
  {
  if (maskData[(i+1)*imageWidth + j+1] == 0)
  {
  Scalar newcolor(rng(255),rng(255),rng(255));
  floodFill(secondResults,mask,Point(j,i),newcolor,0,Scalar::all(1),Scalar::all(1));
  }
  }
  }
  
  imwrite("E:\\firstMeanShift.png",firstResults);
  imwrite("E:\\secondMeanShift.png",secondResults);
  }
