Description

The 2.4.1 release comes with an option to store and retrieve matrices as noted in the release notes
  • Added API for storing OpenCV data structures to text string and reading them back

I think this or similar functionality (maybe by implementing java's Serializable API) might be very useful in the Java API for android.

In my particular case i want to do feature detection on images using SIFT. Now every time i start my application i have to parse all reference images to find keypoints and compute their descriptors. If the keypoints would be serializable this could greatly reduce loading times.

Therefore: Could some persistence functionality, such as serialisation, be implemented for datatypes such as Keypoints or matrices in general?

Just as a notice, this is a feature that also interests me for similar reasons. Although it is not critical for me.

well, part of it has been done on C++ side in OpenCV 2.4.1; there is still some work to do both in C++ and Java wrappers.
