halcon-gray_dilation_rect图像膨胀

在HDevelop中

dev_update_off()

read_image (Image, 'D:/bb/tu/1.jpg')
rgb1_to_gray(Image,Image1)
*将RGB图像转换为灰度图像

gray_dilation_rect (Image1, ImageMax, 5, 5)
*图像膨胀-->效果：增加亮部，减少暗
*参数1：灰度值图像
*参数2：输出图像
*参数3和参数4：结构元的宽和高部

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

在QtCreator中

    HObject  ho_Image, ho_Image1, ho_ImageMax;
    HTuple  hv_Width, hv_Height, hv_WindowHandle;
    HTuple  hv_WindowHandle1;

    ReadImage(&ho_Image, "D:/bb/tu/1.jpg");
    Rgb1ToGray(ho_Image, &ho_Image1);
    //将RGB图像转换为灰度图像

    GrayDilationRect(ho_Image1, &ho_ImageMax, 5, 5);
    //图像膨胀-->效果：增加亮部，减少暗
    //参数1：灰度值图像
    //参数2：输出图像
    //参数3和参数4：结构元的宽和高部

    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_Image1, 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_ImageMax, HDevWindowStack::GetActive());
