Filter Wizard

IronOCR includes an OcrInputFilterWizard class that can automatically evaluate combinations of preprocessing filters to maximize OCR confidence. This is ideal when you're unsure which filters yield the best results. Instead of manually applying contrast, sharpen, binarize, etc., OcrInputFilterWizard.Run(...) performs a brute-force scan for optimal settings and returns the best filter combination or code snippet to reproduce it.
