QR Code Erkennung und Image Traitement
QR Code decoding begins mit Bild Traitement to locate and extract QR Code from Eingabe Bilder. The process includes: grayscale Conversion für simplified Traitement, binarization using adaptive thresholding (Otsu's method) to separate black modules from white background, finder pattern detection (identifying three corner squares mit 1:1:3:1:1 ratio), perspective transfürmation to correct skewed/rotated codes, and module grid detection.
