做游戏出租的网站公司名称大全两个字

• 本案例分3部分
  1. 识别效果,分别显示识别前后识别后;
  2. 代码展示,分别是Halcon源码和Halcon转为C#的代码
  3. 代码解释(解释在源码中)
• 原图如下:

• 处理后的图像:

• Halcon源码：

*读取一张图像
read_image (Image, 'progres')*获取图像大小
get_image_size (Image, Width, Height)*关闭窗口
dev_close_window ()*打开窗口
dev_open_window (0, 0, Width, Height, 'black', WindowID)*显示图像
dev_display (Image)*设置输出对象的颜色,对象是指区域,XLD,其它几何对象
dev_set_color ('red')*设置区域填充方式
dev_set_draw ('margin')*产生矩形ROI
gen_rectangle1 (Rectangle, 260, 90, 360, 350)*减少图像区域
reduce_domain (Image, Rectangle, ImageReduced)*固定阈值
threshold (ImageReduced, Dark, 0, 150)*计算区域里的连通域
connection (Dark, ConnectedRegions)*根据面积大小来过滤区域
select_shape (ConnectedRegions, SelectedRegions, 'area', 'and', 10, 100)*获取区域等效椭圆的参数
elliptic_axis (SelectedRegions, Ra, Rb, Phi)*获取区域的面积和中心坐标
area_center (SelectedRegions, Area, Row, Column)*显示图像
dev_display (Image)*设置输出对象的颜色
dev_set_color ('green')*显示区域
dev_display (SelectedRegions)*计算区域平均半径
MeanRadius := sum(Ra) / |Ra|*计算半径的方差,方差描述随机变量对于数学期望的偏离程度.
VarianceRadius := sum((Ra - MeanRadius)*(Ra - MeanRadius)) / (|Ra|)
