The OcrInput class will automatically resolve low-resolution images for IronTesseract.
Although Tesseract generally requires a 300 DPI input, IronTesseract has been tuned to maintain high accuracy on lower-resolution scans. This can improve OCR speed.
Too high a DPI is slow. Too low a DPI causes inaccuracies. If in doubt, do nothing, and Iron Tesseract will preconfigure everything for you.
How to Improve Low-Quality DPI in Tesseract
- Install the OCR library to improve low-quality DPI.
- Construct an
IronTesseractinstance. - Create an
OcrInputobject with the path to the image. - Choose a target DPI value.
- Invoke the
Readmethod with theOcrInputobject.
