opencv - how to save Mat image in filestorage

opencv

Solution

Writing to file

cv::FileStorage storage("test.yml", cv::FileStorage::WRITE);
storage << "img" << img;
storage.release();

Reading from file

cv::FileStorage storage("test.yml", cv::FileStorage::READ);
storage["img"] >> img;
storage.release();

Problem

I want to save a floating point one-channel image and I don't want to convert it. So I decided to use filestorage class to save it but I couldn't quite get how to do it from the documentation. And what I tried didn't work. Can anybody help me with this? ``` // Write: FileStorage fs("img.xml", FileStorage::WRITE); Mat img; fs << img; // Read: FileStorage fs("img.xml", FileStorage::READ); Mat img; fs >> img; ```
