By use the getList function of class "Algorithm" we can know which algorithm can invoke.But when I use the latest version of opencv the getList result only have one algorithm "CLANE" The code I use as below:

 #include <opencv\cv.h>
#include <opencv\highgui.h>
#include <opencv2\core\core.hpp>
#include <vector>

using namespace std;

int main( int argc, char** argv )
    std::vector<cv::String> algorithms;
    cout << "Algorithms: " << (int)algorithms.size() << endl;
    for (int i=0; i<(int)algorithms.size(); i++) {
        cout << algorithms[i] << endl;

    return 0;


Did U have the same problems?

try calling initModule_ml(); initModule_features2d(); initModule_video(); initModule_contrib();

before getList
