Feature detector issue #457

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?

Javacv is working properly but whenever i try a feature detection or descriptor 
extraction (ORB,SURF,SIFT etc.), i get the following error

my code:

        CvMat testImg = cvLoadImageM("/Users/bsr/test_img.jpg",
                CV_LOAD_IMAGE_GRAYSCALE);
        SIFT sift = new SIFT();
        FeatureDetector featDetect = sift.getFeatureDetector();

        KeyPoint keyPoints = new KeyPoint();
        featDetect.detect(testImg, keyPoints, null);

What is the expected output? What do you see instead?

detected keypoints should be found but get the following error

dyld: Symbol not found:

Does this happen if you use JAR files from the CPPJARs package?

I tried to it. No, it does not happen. I added to CPP jars to my class path and 
the error fixed. Thank you
