Hi all, i'm trying to do feature detection on video frame with opencv4android version.. Now i'm able to create every kind of feature detector using FeatureDetector detector = FeatureDetector.create(FeatureDetector.BRISK); Now my question is, what should i do to set BRISK parameters? As for example the number of octaves and all i can find in the openCV documentation? Hope you'll be able to help me.. Thank you very much Antonio

You should check this answer:

If it doesn't work for BRISK (you have to check which parameters BRISK expects, instead of ORB's ...), it means that right know there is no way to do it for Android.

You need to call the the Brisk-Constructor explicitly, i.e. FeatureDetector detector = cv::Ptr(new cv::Brisk(30, 3, 1.0))

Sorry, I'm not familiar with the Java-OpenCV api. Since the java code is generated from the C++ code it probably works similarly, i.e. something like FeatureDetector detector = new BRISK(30,3,1.0) . Good luck!

causes error on compilation: error: cannot declare variable 'detector' to be of abstract type 'cv::FeatureDetector'. I'm struggling with the same problem.. cannot get BRISK to initialize..
