I am new to Java and Opencv, i have spent 2 days trying to implement BOW in Java, i am using OpenCV 3.2.0 since it is the only version that i found contains BOW classes in Feature2d
int dictionarySize = 1500;
TermCriteria criteria = new TermCriteria(TermCriteria.EPS + TermCriteria.MAX_ITER,100,0.1);
FeatureDetector features = FeatureDetector.create(FeatureDetector.SIFT);
DescriptorExtractor extractor = DescriptorExtractor.create(DescriptorExtractor.SIFT);
DescriptorMatcher matcher = DescriptorMatcher.create(DescriptorMatcher.FLANNBASED);
BOWKMeansTrainer bowTrainer = new BOWKMeansTrainer(dictionarySize, criteria, 1, Core.KMEANS_PP_CENTERS);
BOWImgDescriptorExtractor de = new BOWImgDescriptorExtractor(extractor, matcher);
In the last line of code i found out in Java BOWImgDescriptorExtractor class don't take theses input arguments like
the C++ class.
I need to train SVM with BoW so please any help would be appreciated.
