DSLR RAW data reduction script - Linux - video demo

I may have posted this in the wrong section. DIY, but software. Apologies, forgot about that rule!

New version bottom of this post - minor fix.

I have been at this for several months and notice others doing similar things. While there are Linux astro tools, I decided on the command line capability of dcraw and ImageMagick to perform the reduction task and zenity as a GUI.

It is a bash script and essentially a reduction process for DSLR RAW data - files need to be imported to other programs for deBayering, alignment and stacking. Installation is optional. It can be run from the extracted folder. It will ask the user to nominate or create a new directory for the process.

There is a deBayering, alignment and stacking version of the script using a self similarity interpolation algorithm, but it is 8 bit, terribly slow and proprietary and cant be used otherwise - proof of concept - it works.

align_image_stack does just what its name implies. I would like to use the libdc1394 debayer library for 16 bit interpolation, but not sure how to implement this into bash. I did try bayer2rgb, which is based on the libdc1394 bayer.c library, but the output is screwy, not supported from what I can see and will take a lot of expert work to get working.

My scripting and C++ skills are improving but I am working through the tutorials as I write the code.
