hdf5opencv

http://github.com/dimatura/hdf5opencv

A simple library to save OpenCV matrices as HDF5 datasets and load HDF5 datasets as OpenCV matrices. HDF5 is a standard binary format for scientific data.

I've since extended this library to handle other common types seen when working with ROS, such as PCL point clouds, sensor_msgs point clouds and Eigen matrices. I'll release this someday.
