示例程序源碼（加注釋）

• 關(guān)于顯示類函數(shù)解釋
  dev_update_off ()
  dev_close_window ()
  dev_open_window (0, 0, 512, 512, ‘black’, WindowID)
  set_display_font (WindowID, 14, ‘mono’, ‘true’, ‘false’)
  read_image (Image, ‘particle’)
  dev_display (Image)
  disp_message (WindowID, ‘Original image’, ‘window’, 12, 12, ‘black’, ‘true’)
  disp_continue_message (WindowID, ‘black’, ‘true’)
  stop ()
• 二值化
  threshold (Image, Large, 110, 255)
• 使用圓形膨脹區(qū)域
  dilation_circle (Large, LargeDilation, 7.5)
  dev_display (Image)
  dev_set_draw (‘margin’)
  dev_set_line_width (3)
  dev_set_color (‘red’)
  dev_display (LargeDilation)
  dev_set_draw (‘fill’)
  disp_message (WindowID, ‘Exclude large areas from processing’, ‘window’, 12, 12, ‘black’, ‘true’)
  disp_continue_message (WindowID, ‘black’, ‘true’)
  stop ()
• 求取區(qū)域補(bǔ)集
  complement (LargeDilation, NotLarge)
• 縮減定義域
  reduce_domain (Image, NotLarge, ParticlesRed)
• 動(dòng)態(tài)閾值分割
  mean_image (ParticlesRed, Mean, 31, 31)
  dyn_threshold (ParticlesRed, Mean, SmallRaw, 3, ‘light’)
• 使用圓形元素開(kāi)運(yùn)算
  opening_circle (SmallRaw, Small, 2.5)
• 分割連通域
  connection (Small, SmallConnection)
  dev_display (Image)
  dev_set_colored (12)
  dev_display (SmallConnection)
  disp_message (WindowID, ‘Extracted small particles’, ‘window’, 12, 12, ‘black’, ‘true’)
  disp_continue_message (WindowID, ‘black’, ‘true’)
  stop ()
  dev_set_color (‘green’)
  dev_display (Image)
  dev_set_draw (‘margin’)
  dev_display (SmallConnection)
  Button := 1
• 以下代碼塊完成了鼠標(biāo)點(diǎn)擊到某區(qū)域得到區(qū)域的面積

while (Button == 1)disp_message (WindowID, ['Select object with left mouse button','Right button to quit'], 'image', 5, 5, 'black', 'true')dev_set_color ('green')* 獲取鼠標(biāo)左鍵點(diǎn)擊坐標(biāo)get_mbutton (WindowID, Row, Column, Button)dev_display (Image)dev_display (SmallConnection)dev_set_color ('red')* 使用點(diǎn)坐標(biāo)篩選區(qū)域select_region_point (SmallConnection, SmallSingle, Row, Column)dev_display (SmallSingle)count_obj (SmallSingle, NumSingle)if (NumSingle == 1)* 求區(qū)域平均灰度值intensity (SmallSingle, Image, MeanGray, DeviationGray)area_center (SmallSingle, Area, Row, Column)disp_message (WindowID, ['Area = ' + Area,'Intensity = ' + MeanGray$'.3'], 'image', Row + 10, Column - 90, 'black', 'true')endif endwhile

dev_set_line_width (1)
dev_update_on ()

處理思路

這個(gè)例子是主要講解了通過(guò)鼠標(biāo)實(shí)時(shí)顯示區(qū)域特征的例子。
