opencv的Simpleblobdetector例如素描拋出CV ::例外（-231）

Question

我試圖運行的SimlpeBlobTracker下面的例子素描： https://github.com/spmallick/learnopencv/blob/master/BlobDetector/blob.cpp

然而，當我嘗試運行該程序，

./track 

它打破和回報：

：

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

我用makefile文件編譯

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

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

而且我運行Ubuntu 16和OpenCV 2.4。
