Update July 2021: Added section detailing how Tesseract version can have huge impacts on OCR accuracy.To learn more about using Tesseract and Python together with OCR, just keep reading. By the end of the tutorial, you’ll be able to convert text in an image to a Python string data type.

In the remainder of this blog post, we’ll learn how to install the Tesseract OCR + Python “bindings” followed by writing a simple Python script to call these bindings. Nevertheless, it’s important that we understand how to access Tesseract OCR via the Python programming language in the case that we need to apply OCR to our own projects (provided we can obtain the nice, clean segmentations required by Tesseract).Įxample projects involving OCR may include building a mobile document scanner that you wish to extract textual information from or perhaps you’re running a service that scans paper medical records and you’re looking to put the information into a HIPA-Compliant database.
Hence, we tend to train domain-specific image classifiers and detectors. In practice, it can be extremely challenging to guarantee these types of segmentations. We then applied the Tesseract program to test and evaluate the performance of the OCR engine on a very small set of example images.Īs our results demonstrated, Tesseract works best when there is a (very) clean segmentation of the foreground text from the background. In last week’s blog post we learned how to install the Tesseract binary for Optical Character Recognition (OCR).
