halcon-gray_dilation_shape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_shape (Image1, ImageMax, 5, 5, 'octagon')
*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
*参数5：结构元形状
*       'octagon'    八角形
*       'rectangle'  矩形
*       'rhombus'    棱形

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

  //将RGB图像转换为灰度图像
