There are hundreds of in-depth reviews, open source alternatives to proprietary software from large corporations like Google, Microsoft, Apple, Adobe, IBM, Cisco, Oracle, and Autodesk. The software collection forms part of our series of informative articles for Linux enthusiasts. Our curated compilation covers all categories of software.

Python program to convert all the image files with png extension inside of current directory to txt file. Installation: sudo apt-get install tesseract-ocr. I have tested gocr which didn't work well as compare to tesseract-ocr. The software also has to cope with images that contain a lot more than text, such as layouts, images, graphics, tables, in single or multi pages. Using tesseract-ocr we can extract text from images. Matters are also complicated by the fact that OCR computer software needs very sophisticated algorithms to translate the image of text into accurate actual text. OCR software is not mainstream so open source alternatives to proprietary heavyweight software are fairly thin on the ground. We cover OCR engines as well as front-end tools. This article focuses on desktop, open source OCR software that offer good recognition accuracy and file formats. For some, online OCR services may be useful, but there are privacy concerns and file size limitations. ![]() The selection of the right OCR tool is dependent on specific needs. ![]() ![]() OCR technology is vital for gaining access to paper-based information, as well as integrating that information in digital workflows. The benefit of scanning documents is not purely for archival reasons. There is computer software that makes this conversion possible. Paper documents contain a wealth of important management data and information that would be better stored electronically. Things have changed in the past few years, with a marked shift in the paperless office concept. However, the office environment has shown a resistance to remove the mountain of paper generated. We have witnessed talk of a paperless office for more than 40 years. For example, the vast majority of journeys on the London Underground are made using the Oyster card without a paper ticket being issued. The use of paper has been displaced from some activities. OCR software is able to recognise the difference between characters and images, and between characters themselves. Refer to the below code snippets for a demonstration.Optical Character Recognition (OCR) is the conversion of scanned images of handwritten, typewritten or printed text into searchable, editable documents. Initialize the OCR processor by providing the path of the tesseract binaries(SyncfusionTesseract.dll and liblept168.dll) using ( OCRProcessor processor = new OCRProcessor ( )) Performing OCR on image Place the SyncfusionTesseract.dll and liblept168.dll assemblies (available in the installed location Installation Location\Syncfusion\Essential Studio «version number\ocrprocessor) in the local system and provide the assembly path to the OCR processor. You can perform OCR on a PDF document with the help of OCRProcessor Class. The following namespaces should be added in the application: This assembly contains core feature for OCR the image and PDF document. This assembly compresses the internal contents of a PDF document. This assembly contains the core feature for manipulating and saving PDF documents. To use the OCR feature in your application, you need to add reference to the following set of assemblies: Tesseract OPX, along with Essential PDF, can process the text in images within PDF documents and overlay them with searchable text. NET to be able to process PDF documents with images that contain text. Tesseract OPX is also optimized for working with Syncfusion Essential PDF for. Tesseract OPX makes it easy to use Tesseract with Microsoft. It can be used directly or (for programmers) using an API to extract typed, handwritten, or printed text from images. Tesseract is an open source Optical Recognition (OCR) Engine, available under the Apache 2.0 license. Tesseract OPX in File Formats Introduction ![]()
