Detailed Description

Structure to set 12 preprocessing filters (or less as you need) in some order. Use in C-compatible API. Available filters:

• OCR_IMG_PREPROCESS_BINARIZE
• OCR_IMG_PREPROCESS_GRAYSCALE
• OCR_IMG_PREPROCESS_RESIZE(width, height)
• OCR_IMG_PREPROCESS_DILATE
• OCR_IMG_PREPROCESS_INVERT
• OCR_IMG_PREPROCESS_ROTATE(angle)
• OCR_IMG_PREPROCESS_SCALE(ratio)
• OCR_IMG_PREPROCESS_THRESHOLD(value)
• OCR_IMG_PREPROCESS_MEDIAN

Example:

custom_preprocessing_filters filters;* filters.filter_1 = OCR_IMG_PREPROCESS_BINARIZE;* filters.filter_2 = OCR_IMG_PREPROCESS_ROTATE(20);
