Let say that you have stored the SIFT descriptor in descriptor.xml. Use the following code to assign the saved descriptor back to a Mat variable.

Mat sift_descriptor; 
FileStorage fs("descriptor.xml", FileStorage::READ);
fs["descriptor"] >> sift_descriptor;
fs.release();

You have to save and load Mats that are not images with cv::FileStorage.
