如何在图片框中显示检测到的眼睛？ [英] How to show the detected eyes in picturebox?

问题描述

我使用emgucv进行了眼睛检测。现在我想在单独的图片框中显示检测到的眼睛区域。如何修改此代码呢？

I have done eye detection using emgucv. Now i want to display the detected eye regions in separate pictureboxes. How can i modify this code to do that?

MCvAvgComp[][] eyesDetected = gray.DetectHaarCascade(
                          eye,
                          1.1,
                          10,
                          Emgu.CV.CvEnum.HAAR_DETECTION_TYPE.DO_CANNY_PRUNING,
                          new Size(20, 20));
                       gray.ROI = Rectangle.Empty;

                       foreach (MCvAvgComp ey in eyesDetected[0])
                       {
                           Rectangle eyeRect = ey.rect;
                           eyeRect.Offset(f.rect.X, f.rect.Y);
                           currentFrame.Draw(eyeRect, new Bgr(Color.Blue), 2);

                       }
