You have to scroll down below the capcha, of course. You'll see a
section for list administrators.

At the bottom of that page, underneath the list administrators' link,
where it's easy to mistake it for part of the information for
administrators, is the information you want --

Re: [Gimp-user] image alignment/registration

[Casey Connor]

Ok -- I believe PS is beating align_image_stack because the picture 
seems to have been taken with a very wide lens (i.e. short focal length) 
from close up... as a result, there is a lot of barrel distortion, and 
in addition there is a lot of camera movement between frames, so the 
result is that the image distorts differently from frame to frame and 
align_image_stack is not able to do it automatically. Meaning, when you 
turn the camera that much, it "bends" the contents of the image in 
various different ways that make the images much harder to align. PS 
might be able to automatically correct for that distortion, but 
align_image_stack seems to struggle with it -- I get the same bad 
alignment results you did, but read on for more ideas:


If you can use a longer focal length and stand farther away, and also 
hold the camera more still, I think it will work better (and have less 
barrel distortion as well.) Your PS screenshot also looks like there was 
some kind of contrast or something applied (by PS, I assume? -- maybe 
related to the layer overlay mode when you stack the frames? -- or maybe 
PS is just doing a better job!)


But note this: you don't have to, and probably shouldn't, use the manual 
layer stacking method. That creates a simple averaging of the pixels, 
and it's probably pretty tedious to set up. There is another utility you 
can use to create the median, instead of the average (aka mean), of the 
image, which usually looks better. After I do align_image_stack, I use 
gmic  to take the median of the files. The command line 
looks like this (where test0001.tif etc are the images after alignment):


   gmic -median_files test\*.tif -o output.tif

(you have to use "\*" with wildcards in gmic for whatever reason.)

Then I take the resulting output.tif file, open it in gimp, change the 
precision to 8 or 16bit, and remove the alpha channel (right-click the 
layer). This is the result of that process: 
http://caseyconnor.org/pub/image/aligned_and_medianed.tif


I think it looks pretty good -- maybe not as nice as photoshop, but that 
may just be the "contrast" that PS seems to have added. Note how the 
median, as opposed to the mean, eliminates the most mis-aligned frames 
automatically: those bad frames are left in if you average/mean the 
frames. As mentioned, I think you can make it look a lot better by 
taking better original pictures.


Even if you use PS to align the images, you should look into using gmic 
to take the median, rather than stacking the layers. Just remember that 
gmic outputs 32bit-float RGBA images, and you'll usually want/need to 
convert those to something more common.


(Note: current stable releases of gimp don't support high-precision 
images -- not sure if they will open the 32bit out of gmic or not. I'm 
using 2.9.5.)

But does the image still look ok? If yes, then the layers are there, but
don't show up in the Layers dialog.

The Layers dialog can be set to follow the active image automatically,
or require a manual action to do so - this can be useful if you want to
bring many layers from one image into another, for example.

This is controlled by the bar with a image drop-down and Auto button in
the corresponding dock - see
https://docs.gimp.org/en/gimp-dialogs-structure.html#gimp-layer-dialog

You should check if you have disabled the Auto setting there.

Ah. Thank you so much. I didn't realize the plugins from other sources added to
the existing filter menu. I thought all of those would be under FX or Script FU
menus. They are there now. And thanks for the other reminder. I thought they
were all the same size but when I examined them individually there was one that
was off. Thanks again. I'm a bit new to this intricate of a program so really
appreciate help.

That is why I generally only reply to posts that are obviously from people who
signed up for the forum.

Made an exception for exalted member of Gimp community.

Perhaps it would be better if the mailing list completely blocked the redirect
(if possible) Failing that stop, mailing list participants replying to posts
made by forum members.

I gave up on mailing lists back in early 90's Waste of time once M$ came up with
Outlook and users gave up on properly formatted replies. I am sure you know this
one and it does not apply to you, but how many times do you see a 'thanks'
followed by a page of scrambled posts.

Yes, the mailing list format is terrible for a forum. You see the difference in
user names, Blue is using this forum. White is via a mailing list. Half the time
post are not seen by one side or the other. Then no posting etiquette, top
posting, no editing rules.

There was a typo that I was unable to correct, 'black layer' should have read
'black layer mask'. You will get to layer masks one day.

Sounds complicated for my very basic knowledge. I do not know how to 'stack' or
add a 'black layer' and the restpaint out with a fuzzy brush or where to
access the sharpen dialogue.

I would really like to know how you got two images included with your post;
having a real problem understanding this forum's posting design. Most forums
have an edit button that allows for editing after the post, and the fact that I
cannot get more than one image included with my post is really irksome. Then
there is the captcha malarky at the end of it all; even more irksome.

That, to me, is sort of a no-no. I'd try to pick that up and move it back 
to full visibility in the corner of the finished work so the original 
artist can see that you honored his copyright as opposed to the cutoff.

>Follows Flickr album https://flic.kr/s/aHskT2xjh1

EDIT: I noticed that Flickr automatically changed the tiffs I uploaded into
jpgs, so I wanted to make sure it wouldn't be a waste of time to you.
I did what I suppose you'll do:
1 - Downloaded Flickr album
2 - Aligned the images with align_image_stack
3 - Opened the output from previous step as layers in Gimp.
4 - Changed layers opacity according to the mean rule (100%, 50%, 33%...)
4 - Did the same on PS

Conclusion: The format change didn't interfere in the original alignment issue:
PS correctly auto-aligned the layers, but align_image_stack didn't.

The following images are screen shots from both ps and gimp showing the final
stacks: http://imgur.com/a/drKdB

[Gimp-user] how to change image resolution without effecting scale within the image itself using gimp as in retaining the roundness of the moon

[fenpeppertree]

Here is the in-between image for the other two. The one with the 'ovalish' moon.

Thanks to all for the input, but since there was like 'zero' negative space for
the image, cropping of any sort didn't really work.

What I ended up doing was selecting the moon with the 'elliptical' tool (from
the new 1920 x 1080 image) then copying and pasting it into a 'new' file. From
here I created a circular moon to my liking. I then copied and pasted it over
top of the existing 'ovalish' moon in my 1920 x 1080 image. With some cloning of
the surrounding areas to get rid of the 'oval' moon remnants, I completed the
image. It is now a 1920 x 1080 image with a circular moon, and ready for a my
desktop as a wallpaper.

It works, I guess. I'm sure the other parts of the image are stretched also, but
I can live with those, I guess.

Seems like there should be a way to do this, what seems to be a somewhat simple
task.
I've heard of .svg (scaleable vector graphics) files that supposedly allow for
changing image size while keeping everything the same within the image, but I
have no experience with such files.

Here are my before and after images.
