Hi,
Thank you all so much for the help.
I've managed to generate two separate files that have the same size, using
the "remapped images" option as you suggested. But when I'm layering them
one on top of another and fixing the alignment, the distortions are still
there :-(
At first I thought my control points might be off, and so I checked and
they indeed were - the automatic control points finder did a really poor
job, probably because of the noise one of the images have. So I removed all
control points and added 20 new ones (is this enough?), which are as
accurate as I could find.
Still, generating the images doesn't fix the distortion I get when trying
to align them afterwards.
Is it possible that Hugin is ignoring my control points for some reason?
Maybe I forgot to tick something?
As for align_image_stack, I've tried it but I think it can't find any
control points. That's the output I'm getting:
---
$ align_image_stack -p debug.pto -a stacked 14560002.JPG 14560014.JPG
⏎
No Feature Points
Bad params
No Feature Points
Bad params
An error occured during optimization.
Try adding "-p debug.pto" and checking output.
Exiting...

debug.pto doesn't seem to contain anything useful.
Any ideas for why my control points doesn't seem to fix the distortion? I
believe Hugin is giving them a really bad score (I had to take the
threshold to 0.3 in the preferences panel) but I think it's because of the
noise and the size difference. Do I need to add more maybe?
I'm using Hugin 2014.0.0.5da69bc383dd on Arch Linux for what it matters...
Thanks again.
Yo'av
