GoKawiilReed-Solomon for OCR
Overview
This project provides OCR-optimized error correction for printed codes, coupons, IDs, and labels.
The goal is to print a compact code with Reed-Solomon ECC and OCR-safe parity text. When OCR misreads one or more symbols, the decoder can detect that the scanned code is invalid, identify which symbol positions are inconsistent, and correct the original message when the number of errors is within the configured Reed-Solomon limit.
This is especially useful when the print environment is not ideal. Examples include dot-matrix printers with missing pins, ribbons that are running out of ink, low-resolution printing, labels that easily collect dirt, or any workflow where printed characters can be partially damaged before OCR reads them.
This can improve OCR reliability toward 100% for controlled printed-code workflows, assuming the scan quality is good enough and the number of OCR mistakes does not exceed the correction capacity.
