Two fixes: 1. Always use min-channel for color images instead of gated comparison that was falling back to standard grayscale (which has only 23% contrast for white-on-green VIN stickers). 2. Add grayscale-only OCR path (CLAHE + denoise, no thresholding) between adaptive and Otsu attempts. Tesseract's LSTM engine is designed to handle grayscale input directly and often outperforms binarized input where thresholding creates artifacts. Pipeline order: adaptive threshold → grayscale-only → Otsu threshold Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
