Same training descriptor across multiple platform

If I generate the training descriptors using ORB on OS X and I save them using FileStorage in a file, can I use them in an iOS app to feed a FLANN based matcher?

Should definitely work since opencv tries to be crossplatform as much as possible. Its best if you store them with an opencv mechanism if possible

Hi moster. Yes it seems to work. I'm storing it using the FileStorage and YAML format structure contained in OpenCV framework http://docs.opencv.org/modules/core/doc/xml_yaml_persistence.html. I'm saving the vector of mat that contains the training descriptor for ORB in a yaml file generated by a OS X application. Then I use this file in a video recognition app for iPhone/iPad. Everything seemes fine. Thank you.
