halcon-roberts计算边缘

 

 

在HDevelop中

dev_close_window ()
read_image (Image, 'D:/bb/tu/1.jpg')
rgb1_to_gray (Image, GrayImage)

roberts (GrayImage, ImageRoberts, 'gradient_sum')
*计算边缘
*参数1：输入图像
*参数2：输出图像
*参数3：过滤器类型
*       'gradient_sum'    默认
*       'gradient_max'
*       'roberts_max'

get_image_size (GrayImage, Width, Height)
dev_open_window(10,10,Width, Height,'black',WindowHandle)
dev_display(ImageRoberts)

 

 

在QtCreator中

  //计算边缘

  //参数2：输出图像
  //参数3：过滤器类型
  //      'gradient_sum'    默认
  //      'gradient_max'
  //      'roberts_max'
