Optical Character Recognition (OCR)Discover how to perform Optical Character Recognition (OCR) using OpenCV, Tesseract, Deep Learning, and more by following these OCR guides and tutorials.
In a previous tutorial, we implemented our very first OCR project. We saw that Tesseract worked well on some images but returned total nonsense for other examples. Part of being a successful OCR practitioner is learning that when you see…
