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.

    I would try hugin, manually do it in gimp, maayyybe an imagej plugin could do it, or whip up some octave or python code to do it. also, If you upload the photos somewhere im sure someone would be willing to take a crack at it.

    Note, I think you will probably need to do lens calibration, alignment, then stacking.
