count_obj (Region, Number)
*获取区域集中区域的数量

 

 

 

在Qt Creator中

  HObject  ho_Image, ho_Image1, ho_Region;
  HTuple  hv_Number;

  ReadImage(&ho_Image, "D:/bb/tu/4.jpg");
  Rgb1ToGray(ho_Image, &ho_Image1);
  Threshold(ho_Image1, &ho_Region, (((HTuple(80).Append(87)).Append(206)).Append(195)), 
      (((HTuple(90).Append(100)).Append(228)).Append(205)));

  CountObj(ho_Region, &hv_Number);
  //获取区域集中区域的数量
