You can master Computer Vision, Deep Learning, and OpenCV - PyImageSearch
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 learned how to automatically OCR and scan receipts by: Detecting the receipt in the input image Applying a perspective transform to obtain a top-down view of the receipt Utilizing Tesseract to OCR the text on…

In this tutorial, you will learn how to use Tesseract and OpenCV to build an automatic receipt scanner. We’ll use OpenCV to build the actual image processing component of the system, including: Detecting the receipt in the image Finding the…

One of the most challenging aspects of applying optical character recognition (OCR) isn’t the OCR itself. Instead, it’s the process of pre-processing, denoising, and cleaning up images such that they can be OCR’d. To learn how to denoise your images…

Given that we can detect the writing system of the text, it raises the question: Is it possible to translate text from one language to another using OCR and Tesseract? To learn how to translate languages using Tesseract and Python,…

In our previous tutorial, you learned how to OCR only digits from an input image. But what if you wanted to obtain more fine-grained control on the character filtering process? For example, when building an invoicing application, you may want…

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…

The first time I ever used the Tesseract optical character recognition (OCR) engine was in my college undergraduate years. A dataset comprising diverse textual images is necessary for an OCR project. It enables the OCR system to learn different text…

In this tutorial, we will configure our development environment for OCR. Once your machine is configured, we’ll start writing Python code to perform OCR, paving the way for you to develop your own OCR applications. A text-image dataset is useful…

Optical character recognition, or OCR for short, is used to describe algorithms and techniques (both electronic and mechanical) to convert images of text to machine-encoded text. We typically think of OCR in terms of software. Namely, these are systems that:…
