I use the java impl of opencv 3.1.0 on windows.
I use KNearest with my sample image to train. After training i like to store the train result. But always i get a exception on the knearest.save() call:
Exception in thread "main" java.lang.Exception: unknown exception
at org.opencv.core.Algorithm.save_0(Native Method)
at org.opencv.core.Algorithm.save(Algorithm.java:53)
at omrtest.omr.KMeansOMRReader.train(KMeansOMRReader.java:96)
And not enough - if saving works, how can i load the train data? I do not see any load method.
Thanks in advance.
