GREYCstoration plugin

Hi,

I would like to announce a new great Gimp plugin : GREYCstoration. It can be used for restoring photos. Take a look at examples :

Original examples (with inpainting and resize examples) : http://www.greyc.ensicaen.fr/~dtschump/greycstoration/demo.html (en)

My examples : http://www.girouette-stinner.com/castor/restore.html (fr)

I also compared GREYCstoration to Denoise Deluxe and Noise Ninja, results are very good (I think) :
http://www.girouette-stinner.com/castor/compare.html (fr)

You can try the plugin (version 0.1.1, not all functions are implemented, only restore) :
http://www.haypocalc.com/tmp/greystoration_gimp-0.1.1.tar.gz

The plugin works with Gimp 2.2.x (because it is using preview) and is written in C++.

---

The algorithm is written by David Tschumperlé. Everything is explain in GREYCstoration website :
http://www.greyc.ensicaen.fr/~dtschump/greycstoration/

---

The plugin and the algorithm are under GNU GPL and CeCILL licenses (CeCILL is compatible with GNU GPL licence).

Bye, Haypo

GREYCstoration plugin

Hi,

Tried to install the plugin but I am having some problems. It appears that the normal ./configure && make && make install does not work

Yes, the program don't use the classic autotools. But it is planed.

So I did a make and this appeared to work so I did a make install which also appeared to work. But when I try to use the plugin in GIMP 2.2.3 it is grayed out.

Sorry, I forgot to say that GREYCstoration only work on picture in RGB mode (convert your picture in menu Image > Mode > RGB). It also support RGBA (with alpha channel), but the channel isn't modified.

I am running Gentoo Linux 2004.3 on an amd64 machine configured as a x86_64 machine (IE. 64 bit code). Not sure if that matters so I thought I should give you this info in case it does.

I don't know. You will tell me ;-)

OK this helps. I was trying to use it on a gray scale image.

It appears to not work. I got the following error message about 2/3 of the way through the process:

"GIMP Message

Plug-in "greycstoration" (/home/heng/.gimp-2.2/plug-ins/greycstoration)

requested invalid drawable (killing)"

The image was not a small one (2650x2309) and this message was after about 6 minutes of processing. I used the default settings that the tool opens up with. So I am not sure if this is a general bug or an amd64 specific problem. Also I don't think the preview was working as I could not see any difference no matter how I set the controls.

Most of the images I would use something like on are older photos that I have scanned from large format negatives as gray scale images. These tend to be large images (15 to 20 megapixel). I have been using Neat Image on Windows for this and it can take 10 to 15 minutes to process a single image. So I don't mind this taking a while to process the image if it finishes and does a good job.

You might want to have a look at Neat Image to get some ideas about how to implement your user interface. They have a somewhat cripple demo version that you can download for free. It has a step that, with the help of the user, analyzes the image and gives a starting point for fine adjustments. It is by far the most powerful tool I have used for this to date. If you can come close to this level of power with a GIMP plug-in that would be one less thing I need Windows for and I would be one step closer to not needing Windows at all.

Since I was asking for advice that might have been specific to my situation I contacted you off list. But perhaps I should have stayed on list.
