Hi, I'm trying to find keypoints using BRISK, I want the points to be well distributed across the image so I use the brisk detector + GridAdaptedFeatureDetector. The code is the following:
vector<KeyPoint> kp0,kp1;
Mat framek=imread("/home/raul/Escritorio/fotosPSE2/im190.png",0);
Mat framek2=imread("/home/raul/Escritorio/fotosPSE2/im202.png",0);
Ptr<FeatureDetector> brisk = FeatureDetector::create("BRISK");
Ptr<FeatureDetector> detector = new GridAdaptedFeatureDetector(brisk,300,16,12);
detector->detect(framek,kp0,Mat());
detector->detect(framek2,kp1,Mat());
The problem is that I'm getting this error:
OpenCV Error: Bad argument (No parameter 'threshold' is found) in set, file /home/raul/OpenCV/OpenCV-2.4.9/modules/core/src/algorithm.cpp, line 619

what(): /home/raul/OpenCV/OpenCV-2.4.9/modules/core/src/algorithm.cpp:619: error: (-5) No parameter 'threshold' is found in function set
If I only use brisk without the GridAdaptedFeatureDetector it works fine.
Am I doing something wrong? or is a bug?
Thanks, Raúl
