I build a tool like this with Claude in 2hs, uses Rust with OpenCV crate, egui GUI, PDF output. Basically it steps through a folder with images, finds corners, user presses Space if ok, or adjusts corner if not (about 1 in 20 pages has a corner wrong). Undistort, contrast correct based on histogram, etc. happens automatically. On the last page pressing Space creates a PDF. My brother and I were digitizing medical bills for our mother and everything we tried to do this with out there was meh, cost money or both! It seems as soon as you need PDF anything it's $$$. This is a throwaway tool as we're now more and more getting bills as digital files anyway. My only input was specs, otherwise it's "vibe coded" if you want. But consider that the Rust crate ecosystem is mature and my prof. background is computer graphics. Oh, and I have an image manipulation crate that I wrote for work (closed source for now, unfortunately) that has corner pin with area filtering as a primitive. I was just surprised how possible this is now. This was earlier this year (Opus 4.8 was just out) and while we were photographing the pages with our smartphones Claude wrote the tool.
