Subtraction Technique - Forensic Imaging
#4
The term is 'registration' there is an old Gimp (compiled) plugin for this

https://sourceforge.net/projects/gimp-im...ion-0.5.5/

There is a 32 bit Windows plugin there, should work with the Gimp 2.10.8 from gimp.org

edit: There is a 64 bit compiled .exe in this collection: https://samjcreations.blogspot.com/2018/...-bits.html if you decide to try it.

Years since I last tried so, a quick compile in linux and it takes two layers, a base layer for registration and layer to transform (edit: remembering why it is years since, either works or totally off..)

A made up pair, same patch of floor + a bit of film. Opacity reduced to show the displacement. https://i.imgur.com/qPHZNxM.jpg

Very slow plugin, 10 minutes 1024 iterations on a 4896x3672 pix image. Differencing the layers and a comparison before/after registration. https://i.imgur.com/qyFVoE5.jpg

Might be worth a try.

Apart from Hugin, another application is NIP2. There is a Windows installer https://github.com/libvips/nip2/releases. Bit of a learning curve with this one.

and an example of use: https://www.researchgate.net/figure/44-I..._267266175
