I made a tool that makes it a little easier to verify OCRs of hex dumps (not necessarily hex dumps, but that's what I used it for). I'm not exactly an OCR expert, and just wondering if anyone has seen any similar tools:

You feed in segmented images and labels (as produced by some OCR system) and it'll display all images sorted by their class (so for hex dumps, 0, 1, 2, ... , F), which makes it considerably easier to spot mistakes. (You can then drag and drop images that were OCR'd wrong into their correct position and press a button to regenerate and you'll get a corrected hex dump.) At the risk of sounding spammy, the tools are available at https://blog.qiqitori.com/ocr/monospace_segmentation_tool/ (for segmentation if you don't have segmented images yet) and https://blog.qiqitori.com/ocr/verification_tool/, and here's some documentation (and screenshots) on how the tools can be used: https://blog.qiqitori.com/2023/03/ocring-hex-dumps-or-other-monospace-text-and-verifying-the-result/
