Hey OpenCV/Emgu gurus, I have an image that I am generating contour for, see below. I am trying to generate a color histogram based pruning of search space of images to look for. How can I get the mask around just the prominent object contour and block out the remaining. So I have a 2 part question: How do I "invert" the image outside the contour? Floodfill invert, not? I am confused with all the options in OpenCV. Second, how do I generate a 1-d color histogram from the contoured object in this case the red car to exclude the black background and only generate the color histogram that

I need to detect a spiral shaped spring and count its coil turns. I have tried as follows: Image<Bgr, Byte> ProcessImage(Image<Bgr, Byte> img) { Image<Bgr, Byte> imgClone = new Image<Bgr,byte>( img.Width, img.Height); imgClone = img.Clone(); Bgr bgrRed = new Bgr(System.Drawing.Color.Red); #region Algorithm 1 imgClone.PyrUp(); imgClone.PyrDown(); imgClone.PyrUp(); imgClone.PyrDown(); imgClone.PyrUp(); imgClone.PyrDown(); imgClone._EqualizeHist(); imgClone._Dilate(20); imgClone._EqualizeHist(); imgClone._Erode(10); imgClone.PyrUp(); imgClone.PyrDown(); imgClone.PyrUp(); imgClone.PyrDown();

I have written a program in C# using EmguCV (wrapper of openCV). The program tracks an object using camshift algorithm. A rectangle is drawn around the object. The cursor is moved by center of the rectangle. Input is taken from a webcam. Initially the problem was that the cursor couldn't cover the entire screen. Its movement was limited to frame size. And so i applied a multiplication factor: screenwidth/framewidth for movement in X direction. screenheight/frameheight for movement in Y direction With this the mouse covers entire area. But the mouse movement is not smooth any more. I am unable

If anyone who use Emgu openCv wrapper in .net 3.5 framework,please tell me why this exception appears,Its inner exception is unable to load cxcore.dll. For Emgu CV version <= 2.1, this means the following dlls: cvXXX.dll, cvauxXXX.dll, cxcoreXXX.dll, highguiXXX.dll, opencv_ffmpegXXX.dll, mlXXX.dll and cvextern.dll where XXX is the OpenCV version number. For Emgu CV version >= 2.2 this means the following dlls: opencv_calib3dXXX.dll, opencv_contribXXX.dll, opencv_coreXXX.dll, opencv_features2dXXX.dll, opencv_highguiXXX.dll, opencv_imgprocXXX.dll, opencv_legacyXXX.dll, opencv_mlXXX.dll, opencv

I'm new to OpenCV/EmguCV in C#. I tried a tutorial ( http://fewtutorials.bravesites.com/entries/emgu-cv-c/level-3---live-face-detection ) and the video captureing with the webcam was easy. Now my problem: The tutorial was written for EmguCV 2.x. I'm using EmguCV 3.1 (I like to use the newest). Therefor I used the class Mat instead of the class Image<> . The class Image<> hasn't worked with capture.QueryFrame(); But when I come to face detection, the tutorial says I should use the classes CascadeClassifier and DetectHaarCascade . CascadeClassifier is accepted but DetectHaarCascade is not known.

This must be simple for C++ developers using OpenCV directly. However what I'm using is Emgu (an OpenCV wrapper for .NET) and in the latest version we have the method CvInvoke.FindContours returning void, the output result is passed by parameter reference and is of type VectorOfVectorOfPoint . Here is a simple call: //outputResult is a VectorOfVectorOfPoint CvInvoke.FindContours(inputImage, outputResult, null, RetrType.Tree, ChainApproxMethod.ChainApproxSimple); For RetrType.List mode, we can just convert the result to some array of arrays and loop through all the contours easily. However here
