We usually use a TWAIN scanner to achieve various TWAIN image scanning functions before we can apply OCR reader to extract and decode text from image or document file, such as image acquisition using twain and adjusting and resetting twain device controls. After twain scanning, we use OCR recognition to finish batch recognizing and processing large volume images and documents.
