问题 Does anybody know an up-to-date camera calibration project like http://www.emgu.com/wiki/index.php/Camera_Calibration for the current version of EmguCV (3.0.0)? I need to figure out the coefficients of distortion of a special camera. It would be okay to have a standalone binary. It would also be nice, if there is a documentation about which camera-distorion-model is used. The problem behind the project above is, that it is not up-to-date with current EmguCv, so I can't build it. The target is

问题 Currently, I am facing problem with my EmguCV c# code. I am trying to recognize my images from the database, but its not working. Once my face is detected, its crashing and then this error shows up Additional information: OpenCV: Different sizes of objects. I tried searching for this error but I am clueless. This is my code: //Action for each element detected foreach (MCvAvgComp f in facesDetected[0]) { t = t + 1; result = currentFrame.Copy(f.rect).Convert<Gray, byte>().Resize(100, 100, Emgu

问题 Hey this is my first time using this website, but I a problem. I saw this awesome youtube video about getting ocr to work with vb.net. Here the url: http://www.youtube.com/watch?v=Kjdu8SjEtG0 So I decided to download the emgu libraries, here the url: http://sourceforge.net/projects/emgucv/ I did everything the video say and I get this error: "An error occurred creating the form. See Exception.InnerException for details. The error is: The type initializer for 'Emgu.CV.OCR.Tesseract' threw an

问题 I integrated my project on Visual Studio 2010 with Emgu 3.0 and I'm working on detection object project , but when I'm using MCvFont like the following line I get error because the library is missing , This library is removed from the last version of Emgu or what ? MCvFont f2 = new MCvFont(Emgu.CV.CvEnum.FONT.CV_FONT_HERSHEY_TRIPLEX, 1.0, 1.0); 回答1: Emgu.CV.CvEnum.FONT.CV_FONT_HERSHEY_TRIPLEX can be Emgu.CV.CvEnum.FontFace.HersheyTriplex in Emgu 3.0. MCvFont present in Emgu.CV.Structure at

问题 Non-maxima suppression seems to be a built in component of some openCV functions used for corner detection (like cornerHarris, goodFeaturesToTrack etc.). But, I would like to apply non-maxima suppression directly (on its own) to an image. Is there to achieve this in OpenCV (Emgu CV is what I'm using)? 来源： https://stackoverflow.com/questions/36572304/non-maxima-suppression-in-opencv-emgucv

问题 I want to develop an app for Face detection and recognition from a given photo based on the photos in trained set. Will it possible to do it on windows phone 7 ? Could you please tell me the Open CV support for windows? Please help me 回答1: For the Face recognition, Microsoft and Nokia have develop a Beta "Face SDK" You can try this. You've more Information in the Nokia developper website. For The Open Cv request, I don't understsand wath you want :) But maybe this answer response to your

问题 I am writing a C# application that is GPU accelerated using EMGU's GpuInvoke method. I would like to profile my code and look at the load on the GPU and the amount of GPU memory I'm using, but I'm having trouble finding a good way to do that. It seems like it should be simple, but I can't figure out what I'm missing. Thank you 回答1: Some options: using Performance Monitor perfmon.exe which is the easiest tool to use using tools like GPUZ using a performance kit from the GPU hardware vendor

问题 I need to crop an image without changing its aspect ratio. I am taking picture from CANON1100D using EDSDK. Captured image: Width = 1920 and Height=1280 Aspect ration is 1.5 . but I need picture which aspect ratio is 1.33 . // convert into processing resolution (1600,1200) Image<Bgr, byte> runtime_frm = new Image<Bgr, byte>(frame.ToBitmap(1600,1200)); // also in bitmap processing // Bitmap a = new Bitmap(runtime_frm.ToBitmap()); // Bitmap b = new Bitmap(a, new Size(1600,1200)); It's resizing

问题 I have a HD network camera that I am trying to grab frames over rtsp and using the following code: //in Form_Load Application.Idle += getNextFrame; And the Event Handler: private void getNextFrame(object sender, EventArgs ags) { //where _imgCount is the total image Grabs lbl_Count.Text = _imgCount++.ToString(); // and ibLive is a Emgu ImageBox ibLive.Image = capAxis.QueryFrame().Resize(640, 480, INTER.CV_INTER_AREA); } When I start the program, it'll grab 20-40 frames before the "streakiness"

问题 I am trying to detect a piece of paper from an image. Well I have had help from posts like this . But one difference is that my background color is almost same as the paper color, and I am getting wrong result. [edit] By wrong result I mean the paper outline contour is not detected at all. instead the largest contour covers the whole image. image1 image2 My code so far (using emgu cv and c#) MemStorage storage = new MemStorage(); List<Contour<Point>> candidateList = new List<Contour<Point>>()
