| Collection of utility functions to implement rudimentary template-matching based OCR using OpenCV, | |
| intended for use with large, uniform blocks of monospaced, non-language-correlated text (effectively | |

| example, found themselves needing to recover a hardcopy-printed backup of an OpenPGP key. | |
| Modern general-purpose OCR software doesn't tend to do that well with these, relying heavily on | |
| language-context-based guessing, often trying to be too clever in layout auto-detection, all the while | |
| being extremely tricky to configure precisely enough to allow us to impart our existing knowledge | |
| about the constraints of the target text (expected alphabet, line length, expected font...). |
