HDR imaging

[fabrice senger-2]

Dear all,

I red several times about efforts to develop an HDR tool within imageJ.
Is there something going on in this way ?

Thank you very much,

Fabrice.

Hi Fabrice,
There are some (non-IJ) tools already developed to assemble bracketed
sequences and (more important) to do the tone mapping which is the tricky part
(ie show the HDR data in a low dynamic range device). In linux you have the
hugin tools which are included in several distributions. I played a bit with
those and they seem to work well.

It would be practical to have some plugins to do this, but I guess there might
be little advantage in re-implementing those methods to unless there is some
specific justification (like real time imaging or an automated HDR capturing
setup, or something along those lines).

Cheers
Gabriel

Yes !

I found even stuff with OMERO.

I just wonder why this is still not implemented in imageJ.
Actually I was doing imaging on Neurons some time ago and now went to
cytoskeleton.
In both cases you will face the problem og dense versus thin
structures. At the time being it seems you have to choose what you
look at.
It would be of interest to get all the information and put it together
in one image...

I don't know any HDR implementation in ImageJ. However, depending on
how you acquire images, your scope software may be able to do it
during acquisition. Zeiss (no commercial interest) has implemented HDR
acquisition in their Axiovision software:
http://microscopy.zeiss.com/microscopy/en_de/products/software/axiovision-for-biology/image-acquisition.html
I think something similar exist in the Leica acquisition soft.

Cheers,

Christophe

Hi Fabrice,

a HDR plugin was developed at the Cologne University of Applied Sciences
some time ago. Didn't get to use it on a project so far but it did the
job on some test images I had.
The plugin was developed as product of a bachelor thesis. You can find
the (german only) text of the thesis here:
http://opus.bibl.fh-koeln.de/volltexte/2009/237/

You may contact Dietmar Kunz ([hidden email]) about that, the
student who developed the plugin worked in his group.

Kind regards,

Christian
