Hi,

feature detector fails when used in simple program in visual studio 2010. I am using opencv 2.4.2 and also checked on 2.4.1. Only thing that is being done is to create a feature detector and use that to detect keypoints in an image. I get unhandled exception crash pointing to a function named "detecImpl()" inside detectors.cpp (i.e. features2d\detectors.cpp line:65). This error is really stuck and has taken enormous amount of time so any help is really appreciated.

#include <iostream>
#include <opencv2/core/core.hpp>
#include "opencv2/highgui/highgui.hpp"
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/features2d/features2d.hpp>

using namespace std;
using namespace cv;

int main(int argc, char* argv[])
{
cv::Ptr<cv::FeatureDetector> featureDetector;
    cv::Ptr<cv::DescriptorExtractor> descriptorExtractor;
    featureDetector = cv::FeatureDetector::create("SURF");
    descriptorExtractor = cv::DescriptorExtractor::create("SURF");
cv::Mat imageColor;
cv::Mat image = cv::imread("car1.jpg", 0);
    cv::cvtColor(image, imageColor, CV_GRAY2BGR);
    try{
        imshow("Test Image",imageColor);
        cv::waitKey(3000);
    }
    catch(cv::Exception exc)
    {
        cout << "CV error occured : " + exc.msg;
    }
std::vector<cv::KeyPoint> currentKeypoints;

try{
            featureDetector->detect(image,currentKeypoints);   //This line generates the error but no exception is caught ....
    }
    catch(cv::Exception exc)
    {
        cout << "CV error occured : " + exc.msg;
        return -1;
    }
}
