I tried to run the following example sketch for the SimlpeBlobTracker: https://github.com/spmallick/learnopencv/blob/master/BlobDetector/blob.cpp

However, when I try to run the program, 

./track

it breaks and returns:

OpenCV Error: The function/feature is not implemented () in detectAndCompute, file /home/sixtimesseven/Desktop/opencv/opencv/modules/features2d/src/feature2d.cpp, line 144 terminate called after throwing an instance of 'cv::Exception' what(): /home/sixtimesseven/Desktop/opencv/opencv/modules/features2d/src/feature2d.cpp:144: error: (-213) in function detectAndCompute

I am compiling with a makefile:

CFLAGS = `pkg-config --cflags opencv`
LIBS = `pkg-config --libs opencv`

track : track.cpp
    g++ $(CFLAGS) -o track track.cpp $(LIBS)

And I am running Ubuntu 16 and OpenCV 2.4.

I am not an expert on this topic, but I did come across this, which suggests that it might be something related to how you're declaring a certain object.
