How to save the flann index in opencv for java

Hello,

Can someone help me to save a trained flann index?

In time I serialize all descriptors to json and reoad all descriptors after the program is started.

For a lot of descriptors this takes a long time.

Is there another method to save the flann index with java?

did you mean a DescriptorMatcher ? (afaik, flann::index is not avilable in java)

Can I use JavaCV to save a trained index?

idk. javacv != opencv' s java wrappers. unsupported 3rd party api.

okay sorry, yes the DescriptorMatcher has read and write methods but I think it only used to load the properties for the matcher (algorithm,...)
