Does anyone here know a self hostable service (or a demo of someone else hosting it) which can split common .cbr filetype to a .cbz or other filetype to split the panels?
So for example the 1 image I put with this post, would be 8 seperate images (pages).
That would ideally somehow make the comic books readable on a (somewhat old) black and white travel-Kobo…
isnt this more of an image vision task than a aimple utility task?
I’d be amazed if each of those panels coordinates were annotated somewhere
i don’t know any on computer but some app offer that on android/ios. i guess they look for some kind of contrast pattern to determine each frame Did try and it does work really well on some but not all garphics novel / comics
What’s the name of the app you tried?
the coordinates aren’t there i think, but there are github projects out there that “detect” the panels and suggest split based on that. For most of the panels of most of the comics, that would be more than enough to do a clean split. I just can’t find a real relatively easily deployable service that incorporates it.
Just following your above link, you could pre-convert your comics using this: framagit.org/nicooo/kumiko

This isn’t a thing because there are many comics that don’t adhere to “frames”. They overlap with others, use the whole page, etc.
But beyond this, decompress your CBR/cbz files and use imagemagick to find frames and isolate them.

This is a thing. It just doesn’t work very reliably for the reasons you mentioned.
It does work kind of ok on some comics like the one OP shared and generally pretty well on manga since that tends to be more consistent with the boxes.
I don’t know of anything open source or self hosted that does this though.

Even in the page given as an example here there are two speech bubbles that are pushing their boundaries.
