Image Binarization for Receipt Printing: Algorithms and Implementation

The article outlines a receipt‑printer image binarization pipeline that converts color logos and QR codes to black‑white bitmaps by first reviewing a C‑based OTSU implementation, then introducing a parallel trio of OTSU, average‑gray, and double‑peak algorithms whose outputs are compared via hash fingerprints, cached for reuse, and optimized for speed on mobile devices, with plans for adaptive thresholds and block‑wise QR processing.
