- Binarization converts images to black and white, setting each pixel to 0 or 255.
- Two main binarization methods: Global (single threshold) and Local (varying thresholds per pixel).
- Otary offers 5 basic and 12 advanced binarization methods.
- Basic methods include simple, otsu, adaptive, bradley, and sauvola, accessible via the Image object.
- Advanced methods are available through the transformer.binarizer attribute.
- BinarizerImage class includes two global (threshold_simple, threshold_otsu) and multiple local thresholding methods.
- Sauvola method is generally the best but slower; adaptive or otsu are best for speed and quality.
- Various thresholding methods like adaptive, adotsu, bradley, feng, gatos, isauvola, niblack, nick, otsu, phansalkar, sauvola, simple, singh, su, wan, and wolf are detailed with parameters.
