i try to use Align layers to align three misaligned photos, but i can’t get it to work.
Here is my workflow
Load pictures as layers
Open G’MIC QT → Layers → Align layers
Set smoothness at minimum
Input layers → All
Everything else left on default
Preview shows aligned image
Click OK, then there is processing for 5 seconds
No aligment on my images
I try do do similar thing as Auto align layers in Photoshop does.
I also tried align_image_stack from Hugin, and it’s working perfectly. But i want to use one software if it’s possible.
So my question is, why is this plugin not working ? Is there some bug, or is there something what i need to do before or after this plugin is used ?
They are only for my testing, that’s why every image has different WB and is intentionaly misaligned. That way i can see if they are aligned when i set layer opacity to 50%
Thanks, that’s interesting.
When reducing the resolution (to 1024 px width) for a quick test, I got acceptable results with this filter. When I let the original resolution (6000 px width), it doesn’t work anymore.
I’ll check this later, but this seems to be a bug in this quite old (2010) filter.
Just tried myself this plugin (G.MIC 2.8.0 with Gimp 2.10.14 on Windows 10).
I can not get it working either.
From its name I suppose I should get a new layer (or image) with all my layers aligned (stacked on top of each other)
Here is a Dropbox link with a ZIP folder with 3 jpeg images to align in case you need them for some more testing:
Dear David, it does not work for me, also after the update. GIMP 2.10.14, G’MIC 2.9.0 on Windows. Preview shows the right alignment, but the output layers are not aligned.
Just out of curiosity, I have just tested myself this filter.
I also run G’MIC 2.9 with GIMP 2.10.18 (on Windows 10).
To test this filter I have downloaded the ZIP with 3 jpeg images: see 3° message of Komodo Martin, on this same thread, where he posts his link on Nextcloud (GMIC-Align).
On my setup it works.
In that all 3 layers are correctly aligned.
Maybe I’m doing smth. wrong. I’he tryed all possible setups, Rigid, Non-Rigid, smoothness from 0 to 1, it does nothing. The resulting layers are just equal to the input layers, their position did not change.
Just tested on:
Windows 10 (64 bit)
GIMP 2.10.18
tested both G’MIC 2.9 and G’MIC 2.8.4
I have downloaded the GMIC_ALIGN zip file from this same post in order to have a commun base to check the 3 jpeg images within this folder.
With both 2.9 and 2.8.4 G’MIC versions the 3 layers (jpeg of the zip) are not cropped.
When you check with GIMP the result, the 3 layers look aligned though (but are not cropped to make them fit).
In the past I recall they were also cropped to fit them.
I’he set input mode to “all visible layers”.
I found also an interesting issue, the alignment works sometimes for images which was previously edited by Hugin’s software.
If I take the *.jpg images directly from my camera, the alignmet doesn’t work. Here you can try my set: https://drive.google.com/open?id=1p__ckKxdzL6yYpssZx-oPKg01meJOXWm
Thanks @Wladimir_K for providing me the data to reproduce the bug.
It seems the phase correlation method I’m using for registering the images doesn’t work quite well with large images. I’ve made a fix, and currently generating the filter update with it.
Maybe you could check in a few minutes (10-15 maybe), by refreshing your filters, and try the filter again, with the rigid mode.
Waiting for your feedback
