.Net OCR Library

Iron OCR has been specifically designed for use in .NET applications, including console applications, Windows Form Applications, WPF, and web applications such as Windows Forms and MVC. It is built on top of the Tesseract platform, but adds additional functionality, making Tesseract more usable in the real world. https://ironsoftware.com/csharp/ocr/technology/ocr-net/ and https://www.nuget.org/packages/IronOcr/

Iron OCR has been designed with developers in mind, allowing for rapid OCR setup within .NET projects. OCR requires a lot of preprocessing of images to make them readable by OCR libraries, which expect almost perfect input.

Iron OCR can automatically detect the properties of an image, a screenshot, photographs, scans, or PDF document and adjust itself accordingly, preprocessing the images so the OCR is likely to have over 95% accuracy without any settings being adjusted or any Photoshop work on behalf of the client organization.

Language packs are available for multiple languages including: Language packs available for Arabic, Simplified Chinese, Traditional Chinese, Danish, English, Finnish, French, German, Hebrew, Italian, Japanese, Korean, Portuguese, Russian, Spanish, and Swedish. Language packs can be found here: https://ironsoftware.com/csharp/ocr/languages/

Iron OCR can be used with many other Iron products. It is commonly used with Iron Barcode. Iron OCR may be used to extract text from a document, whereas Iron Barcode can be used to detect barcodes with a higher degree of accuracy within a similar scan.

It may also be used with Iron PDF to repurpose content from scanned documents in new PDF documents. For more information, support, licensing questions please contact Iron Software. Product information can be found on the product page: https://ironsoftware.com/csharp/ocr/

How to Read Text from an Image in C#

To Recognize Text From Image in C#, the first step is to install Iron OCR (https://ironsoftware.com/csharp/ocr/tutorials/how-to-read-text-from-an-image-in-csharp-net/). This is most easily achieved using the NuGet Package Manager using the ID name OCR for the package we wish to install (https://www.nuget.org/packages/ocr).

The Auto OCR class is a .NET class allowing OCR to be achieved in a single line of code. It can read text from images in C# .Net with very little setup, and Iron OCR will automatically make a best guess at all of the correct configuration and image cleanup operations required for a good OCR operation and clean text to be extracted from an image.

The Advanced OCR class can be used for advanced OCR operations to read text from an image in c#. It allows us to extract text from images, TIFFs, scans and photographs, and even PDF documents. Within the tutorial, we have source code for dealing with different situations where we have low, medium, and high quality scans, and also look at how we can correct for digital noise, skew, perspective, and rotation.

The next section of the tutorial shows how we can optimize Iron OCR in C# for the fastest result, although there is always a balance between speed and OCR accuracy.

We move forward to look at how we can use Iron OCR and C# to extract international text from documents using non-English scripts. We show how to install language packs such as Arabic, Spanish, and Chinese.

The last part of the tutorial shows how we can drill down into the OCR results using C# code. This allows us to see pages, paragraphs, lines, words, characters, and even barcodes found within a document. We can look at their typeface, statistical accuracy, location, and even return an image for that object.

We have learnt how to convert an image to text in c#. This project provides full source code available as a ZIP file as well as a GIT Repository where the C# source code can be viewed and modified by developers.
