    Please can some expert person explain me whether we can use the cvHaarDetectObjects() method to detect squares and get width and heights? I found a code that use this method for face-detection but I need to know whether I can use it for rectangle detection.String src=”src/squiredetection/MY.JPG”;IplImage grabbedImage = cvLoadImage(src);IplImage grayImage = IplImage.create(grabbedImage.width(), grabbedImage.height(), IPL_DEPTH_8U, 1);c

    It’s the first day of learning JavaCV for me. And this is the first test example which I use just to make sure that my setup is done correctly. Unfortunately I can’t run the example and I barely understand the code and all dependencies so it’s really hard for me to find out what is missing. Below I’ll post my project setup and also the errors I get.Also the example I use is from: http://ganeshtiwaridotcomdotnp.blogspot.com/2011/12/javacv-capture-save-flip-show-live.htmlcodeimport static com.googlecode.javacv.cpp.opencv_core.cvFlip; import static com.googlecode.javacv.cpp.opencv_highgui.cvSaveImage; import com.googlecode.javacv.CanvasFrame; import com.googlecode.javacv.FrameGrabber; impor

    I’m trying to fit an ellipse to a set of 2D integer points in javacv and keep running into problems. So my question is, what kind of data does cvFitEllipse2 expect?From OpenCV’s manual I found thatCvBox2D cvFitEllipse2(const CvArr* points)Parameters points – Input 2D point set, stored in:std::vector or Mat (C++ interface) CvSeq* or CvMat* (C interface) Nx2 numpy array (Python interface)I have tried both CvSeq as well as CvMat the following way:1 CvSeqCvMemStorage mem = cvCreateMemStorage(0); CvSeq seq = cvCreateSeq(0, Loader.si

    java opencv javacv unsatisfiedlinkerror
    I have made a application to grab video from a webcam and detect motion using OpenCV and JavaCV. I am trying to export as an executable jar using eclipse. The program runs fine in eclipse as does the exe jar on the computer I coded the program on. What I am trying to accomplish is to make the exe Jar run on computers that don’t have OpenCV installed. Basically what I would consider a portable application. When I run the exe jar on a different computer that has nothing installed other than the JRE I get unsatisfied link errors seen below.Exception in thread “Video Thread” java.lang.UnsatisfiedLinkError: C:\Users\JohnD\AppData\Local\Temp\javacpp91062429652918\jniopencv_core.dll: Can’t find depende
