From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Reconstruction of an image from a stack of images (lemmy.ml)

I took several photos of a drawing that a friend had made, but the quality of the photos is not very good, so I need software that can produce enhanced images by combining a stack of images of the same scene that were taken during a short period of time.

Another comment from my side: I think it would be best if you share some of the images, or at least describe what problems they have.

Is the resolution not high enough? --> Try Upscayl
Are they blurry? --> Good luck. Rescuing blurry pictures, either because of motion blur or lack of focus, is the hardest/ almost impossible thing in photography. You could try some "AI" tools, depending on how sharp the image is, but they usually suck.
Are they noisy? --> Maybe try Topaz Denoise (paid and proprietary) or GIMP/ Darktable (FOSS, but not exactly as sophisticated or quick). Sadly, canceling out noise usually results in a "watercolor" look if overdone.
Or do yo just want to recover information? -> Increase contrast, sharpness and middle tones.

Either way, since you asked specifically in c/Linux (which I find a bit unfitting personally, better ask in c/Photography), I can recommend 3 Tools:

GIMP of course, maybe with plugins, for general editing, and Darktable for post-processing (color grading, sharpening, etc.) your images. The latter one works best with RAW images, which you probably don't have since you shot on a phone.
Upscayl for Pixel interpolation (usually doesn't increase sharpness, just the pixel count if yo want to crop more or print a poster at higher resolution).
And maybe Huggingface, which also offers quite some image processing AI stuff.

But as I said, please provide some pictures, or at least more information. Just saying "muh pics bad" is almost worthless for me.
