12/29/2023 0 Comments Convert png to text![]() The string ‘en’ stands for the English language. The parameter in the bracket indicates the language of the image text. Once Tesseract is set up, you must install the pytesseract library, which acts as a Python wrapper for Tesseract along with OpenCV. You can install it by following the instructions specific to your operating system. To begin, install Tesseract on your system. You can use Tesseract and OpenCV to extract information from images using Python. OpenCV is written in C++ and offers interfaces for various programming languages, including Python. Open Source Computer Vision Library (OpenCV) is a machine learning software library that provides various functionalities and algorithms to work with images and videos. Tesseract is a widely used open-source OCR (Optical Character Recognition) engine that provides accurate text extraction from images. The methods outlined below will work well for simple images. You have to preprocess the text before extraction and then further analyze and correct the text after extraction. Such images are going to require much more coding and testing efforts in a DIY coding program. Such images have large text, less words, simple font and clear contrast between text and images. You may just need a few lines of code if you expect an input of simple images, like the ones shown below. ![]() However, the code complexity and output accuracy can vary greatly depending on the input you expect. Technically, you can extract text from all types of images in Python. What Types of Images Can You Extract Text From? Identifying location details from images of places-like street signs, store names, and so on.Scanning food labels and ingredients when adding products.Automatic scanning of ID documents like passports, voter IDs, and rental agreements as part of authorization and authentication workflows.Digital conversion of resumes and forms for recruitment and other HR processes.Digital conversion of healthcare records, scans, and images.Other use cases for text extraction include: You can store the data for tax and audits or use it to analyze supplier performance. You have to extract the text or convert it into string data type so you can store and use the data.įor example, you can extract supplier information, invoice date, invoice amount, and other text information from invoice images. ![]() ![]() The text in the image scans is not searchable, editable, or useful for analysis. Many organizations have image data that is scanned from operational paperwork. Let’s begin by understanding why you need to convert images to text! We also look at limitations of some common methods and suggest practical ways to improve the output. This article looks at different types of images and methods to extract text from both simple and complex images. You can use AI-powered optical character recognition (OCR) algorithms to accurately extract text from images and make your data more accessible, searchable, and actionable. However, with the advancements in artificial intelligence (AI), you now have the ability to automate this process using code. Extracting relevant text information from these files manually is time-consuming, error-prone, and inefficient. Modern organizations are inundated with vast amounts of unstructured data in the form of images, PDFs, and scanned documents.
