halcon-開運算(先腐蝕再膨脹)

 

 

開運算：對區域先進行腐蝕操作，然后對腐蝕的結果再進行膨脹操作，稱為開運算
開運算特點：具有與腐蝕相似的特點，但是能夠防止區域腐蝕過度，能夠很好的保持區域的形狀。

效果：能去除毛刺

opening_circle區域圓開運算 

在HDevelop中

dev_update_off()

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

threshold (Image1, Region, 200, 230)
opening_circle (Region, RegionOpening, 2.5)
*區域圓開運算
*參數1：要開運算的區域
*參數2：輸出區域
*結構圓半徑


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)
