halcon-dilation_circle圓形區域膨脹

膨脹特點：對於填補圖像分割后物體的空洞以及區域邊界的凹陷區域具有很好的效果
膨脹分類：根據膨脹結構元的形狀，在halcon中分為圓形膨脹以及矩形膨脹等

在HDevelop中

dev_update_off()

read_image (Image, 'D:/bb/tu/1.jpg')
rgb1_to_gray(Image,Image1)
*將RGB圖像轉換為灰度圖像

threshold (Image1, Region, 200, 230)
dilation_circle (Region, RegionDilation, 3.5)
*圓形膨脹
*參數1：需要膨脹的區域
*參數2：輸出區域
*參數3：結構元大小



get_image_size (Image1, Width, Height)
dev_open_window(10,10,Width, Height,'black',WindowHandle)
dev_display(Region)
dev_open_window(10,100,Width, Height,'black',WindowHandle1)
dev_display(RegionDilation)

  

在QtCreator中

    HObject  ho_Image, ho_Image1, ho_Region, ho_RegionDilation;
    HTuple  hv_Width, hv_Height, hv_WindowHandle;
    HTuple  hv_WindowHandle1;

    ReadImage(&ho_Image, "D:/bb/tu/1.jpg");
    Rgb1ToGray(ho_Image, &ho_Image1);
    //將RGB圖像轉換為灰度圖像

    Threshold(ho_Image1, &ho_Region, 200, 230);
    DilationCircle(ho_Region, &ho_RegionDilation, 3.5);
    //圓形膨脹
    //參數1：需要膨脹的區域
    //參數2：輸出區域
    //參數3：結構元大小



    GetImageSize(ho_Image1, &hv_Width, &hv_Height);
    SetWindowAttr("background_color","black");
    OpenWindow(10,10,hv_Width,hv_Height,0,"visible","",&hv_WindowHandle);
    HDevWindowStack::Push(hv_WindowHandle);
    if (HDevWindowStack::IsOpen())
      DispObj(ho_Region, HDevWindowStack::GetActive());
    SetWindowAttr("background_color","black");
    OpenWindow(10,100,hv_Width,hv_Height,0,"visible","",&hv_WindowHandle1);
    HDevWindowStack::Push(hv_WindowHandle1);
    if (HDevWindowStack::IsOpen())
      DispObj(ho_RegionDilation, HDevWindowStack::GetActive());
