Try getting the OpenCV 2.3.1 superpack <a href="http://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.3.1/" rel="nofollow">here</a>. If that is still giving you trouble, I would try compiling OpenCV from source using <a href="http://cmake.org/cmake/resources/software.html" rel="nofollow">CMake</a>. Follow <a href="http://opencv.willowgarage.com/wiki/InstallGuide" rel="nofollow">this guide</a> to build OpenCV from source. Aside from the obvious problem of the DLL not being in the same directory as the executable, this looks like it might be a mismatch between the compiled binary architecture (i.e., 32-bit/VS2005 vs. 64-bit/VS2010) and the one you are running. Hope that is helpful! EDIT : Can you try compiling and running this code (this is working perfectly on my system)? Make sure you use the 2.3.1 version for this one. <pre><code>#include <opencv2/core/core.hpp> #include <opencv2/highgui/highgui.hpp> #include <opencv2/imgproc/imgproc.hpp> #include <opencv2/features2d/features2d.hpp> #include <vector> using namespace std; using namespace cv; int main(int argc, char* argv[]) { Mat image = imread("yourimage.jpg", 0); Ptr<FeatureDetector> detector = FeatureDetector::create("FAST"); vector<KeyPoint> points; detector->detect(image, points); Mat imageColor; cvtColor(image, imageColor, CV_GRAY2BGR); drawKeypoints(imageColor, points, imageColor, Scalar(255, 0, 0), DrawMatchesFlags::DRAW_OVER_OUTIMG); imshow("imageColor", imageColor); waitKey(); return 0; } </code></pre> Can you also post a link to the image you are trying to run feature detection on? Also, how are you creating your project in Visual Studio?

1. COWith OpenCV 2.3.1 I get a different (and mysterious at the same time) error (see above). About the architecture I think is not related because I tested the same code both on a 32-bit VS10 and a 64-bit VS10.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
