2019-11-01 07:40:54 -0600	commented answer	cv::Algorithm read/write in API 3? Thanks for the reply. If they are not deprecated, then they can certainly be used as you say. Thanks for the examples.
2019-11-01 07:37:10 -0600	marked best answer	cv::Algorithm read/write in API 3? Hi I am using cv::ml::RTrees to train a Random Forest model and predict some values. I'd like to store the final trained model in some custom structure and also to write ToString and FromString methods. I have seen that API version 2 has read/write methods and a FileStorage structure which would help to read/write from string but I have read that these are deprecated in API 3. Is this true? And if so, are there any alternative methods provided to replace those (save/load are not valid answers here, as these store and read from file which I don't want to do)? Also, does OpenCV provide any class or set of classes to access the final trained model (e.g. trees, nodes, values) so that I can safely store the model in code without any need to train again? Thanks in advance for your help.
