CvKNearest extends CvStatModel hence it has save and load-methods. Why don't you simply use those methods? Do you have to update your trained model? That would be a problem...

2015-03-13 04:59:13 -0600 answered a question The opencv Mat object (java)

The array "data" gives you the result of a single element of the Mat object. Thus, your initialization is wrong:

byte[] data = new byte[(int)mat.elemSize()];

However, if you're using a Mat with a single channel only you may also ignore the array:

System.out.println(mat.get(0, 0, new byte[(int) mat.elemSize()]));

2015-03-11 05:51:40 -0600 asked a question Is it possible to use a prosilica camera in java?


since not all functions of openCv are available under Java I wonder if it is possible to simply use a Procilica Gig-E camera under openCV in Java. Any experiences with this?

I'd like to save a CvRTrees object in a db-field (in java). However, the only way to get the XML structure seems to be saving it into a xml-file. Any suggestions how I can get a Tree (or Support Vector Machine) as a XML String without writing it into a file?

Thanks, I implemented it with CvRTrees.

I'd like to use a decision tree for classification in java (using opencv 2.4.6) but the CvDTree is missing the predict method (same in the current version. See doc: What is the reason for this? Any alternatives for classification? Random trees?
