halcon-add_noise_white添加噪声

在HDevelop中

ma.jpg

 

 

read_image (Image, 'D:/bb/tu/ma.jpg')
add_noise_white (Image, ImageNoise,20 )
*添加噪声--均匀分布
*参数3：最大噪声幅度，建议值：1.0,2.0,5.0,10.0,20.0,40.0,60.0,90.0,值越大噪声越多



dev_open_window(0,0,650,488,'black',WindowHandle)
dev_display(ImageNoise)

 

 

在Qt Creator中

    HObject  ho_Image, ho_ImageNoise;
    HTuple  hv_WindowHandle;

    ReadImage(&ho_Image, "D:/bb/tu/ma.jpg");
    AddNoiseWhite(ho_Image, &ho_ImageNoise, 20);
      //添加噪声--均匀分布
      //参数3：最大噪声幅度，建议值：1.0,2.0,5.0,10.0,20.0,40.0,60.0,90.0,值越大噪声越多



    SetWindowAttr("background_color","black");
    OpenWindow(0,0,650,488,0,"visible","",&hv_WindowHandle);
    HDevWindowStack::Push(hv_WindowHandle);
    if (HDevWindowStack::IsOpen())
      DispObj(ho_ImageNoise, HDevWindowStack::GetActive());
