Experimental Physics and
Just out of curiosity, why would you store images in hdf5 files?
How do you store them? 1 image = 1 huge table with pixel intensity?
It must be because it is easier to get statistics, extract region of interest, work with several images (datasets), etc.
Is that correct?
For a project, I worked on some time ago (but dropped due to lack of funding), we were looking at CT-scan type of applications with 8 exposures per rotation angle, 180 deg rotation with 0.5 deg step, i.e. descent size data set. I am wondering if hdf5 could have helped in the reconstruction. Then and still today, we were/are using mar/crayonix software.
MAR doesn't store image in hdf5 format, but can the areaDetector package convert those files on the fly?

Subject: RE: hdf5 (h5py) anyone?
The EPICS areaDetector package currently has 2 file writers that produce HDF5 files:
NDFileNexus creates NeXus compliant HDF5 files using the NeXus API. It was written by John Hammonds from the APS.
NDFileHDF5 creates HDF5 files using the native HDF5 API. It was written by Ulrik Pedersen from Diamond Light Source
