本文介绍了什么是寻找大津阈值emgu品种的功能？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我不需要阈值的图像。我想要的门槛。我发现这个在OpenCV中
I don't need the thresholded image. I want the threshold. I found this in OpenCV.
cv::threshold( orig_img, thres_img, 0, 255, CV_THRESH_BINARY+CV_THRESH_OTSU );
是否有EmguCv等效。先谢谢了。
Is there an equivalent in EmguCv. Thanks in advance.
PS。我需要使用此阈值Canny边缘检测
PS. I need to use this threshold for canny edge detector
推荐答案
您可以参考进行自动Canny边缘检测的代码！
You can refer this code for Auto Canny Edge detector!
Image<Gray, byte> Img_Source_Gray = Img_Org_Gray.Copy();
Image<Gray, byte> Img_Egde_Gray = Img_Source_Gray.CopyBlank();
Image<Gray, byte> Img_SourceSmoothed_Gray = Img_Source_Gray.CopyBlank();
Image<Gray, byte> Img_Otsu_Gray = Img_Org_Gray.CopyBlank();
Img_SourceSmoothed_Gray = Img_Source_Gray.SmoothGaussian(3);
double CannyAccThresh = CvInvoke.cvThreshold(Img_EgdeNR_Gray.Ptr, Img_Otsu_Gray.Ptr, 0, 255, Emgu.CV.CvEnum.THRESH.CV_THRESH_OTSU | Emgu.CV.CvEnum.THRESH.CV_THRESH_BINARY);
double CannyThresh = 0.1 * CannyAccThresh;
Img_Otsu_Gray.Dispose();
Img_Egde_Gray = Img_SourceSmoothed_Gray.Canny(CannyThresh, CannyAccThresh);
imageBox2.Image = Img_Egde_Gray;
