Tesseract is an open-source OCR Enginethat extracts printed or written text from images. It was originally developed by Hewlett-Packard, and development was later taken over by Google. This is why it is now known as “Google Tesseract OCR”. But what is an open-source OCR? It simply means that it is available for everyone to use freely, either direct...
So far, we know that Pytesseract is a wrapper for Google’s Tesseract OCR in Python with additional functionalities that Tesseract alone does not have. So what are these functionalities, and how does it work? Pytesseract can be used as a standalone script for Tesseract allowing it to print recognized text instead of converting it to a file. Pytesser...
If you are in a business that processes documents from customers, suppliers, partners, or employees, chances are that you can improve your document processing workflow with Tesseract OCR. Below we have listed a few of the use cases in which Python OCR can be applied. 1. Automated Data Entry– Bottlenecks are often caused by tedious tasks such as dat...
In cases where Tesseract does not support your data extraction needs out-of-the-box, you have to train the OCR engine yourself. What this means practically is that you would need to have thousands of example images or documents annotated to train Tesseract OCR. This is also called “training data”. Not all organizations have training data available ...
Tesseract OCR can be very useful in many instances and use cases. However, like any other open-source solution, there are always some drawbacks to consider. In this section, we will shed light on these limitations one by one: 1. Tesseract is not as accurate as more advanced solutions embedded with AI 2. Tesseract is prone to errors if the separatio...
Klippa DocHorizonis considered to be the next evolution of OCR technology. With over tens of thousands of development hours, the solution has been polished to serve customers in multiple industries.

Apr 23, 2024 · Tesseract OCR is an open-source optical character recognition engine that is the most popular among developers. Like other tools in this list, Tesseract can take images of text and convert them into editable text.
May 25, 2020 · In the first part of this tutorial, we’ll discuss the concept of text detection and localization. From there, I will show you how to install Tesseract on your system. We’ll then implement text localization, detection, and OCR using Tesseract and Python. Finally, we’ll review our results.
