VB .NET OCR is a complex and difficult task that is performed by the IronOCR OCR component for C# and VB .NET. It supports .Net Framework and will soon be released for .NEt Core and .Net Standard. https://ironsoftware.com/csharp/ocr/technology/ocr-vb-net/. and https://www.nuget.org/packages/IronOcr/
Iron OCR implements a full API, allowing developers to read text from images in a single line of code using the Auto OCR class or with advanced setup using the Advanced OCR class within the Iron OCR namespace.
Iron OCR fully supports the PDF standard and allows PDF documents to be read back to text, even if they are encrypted. For high performance, Iron OCR uses multithreading when reading PDF pages using one thread per page.
Iron OCR can be installed using a single reference to the Auto OCR class, and an entire document can be read back to text again using a single line of code using AutoOCR.Read.
Iron OCR differentiates itself in two functions primarily, its ease of use to install because it doesn't require platform-specific setup for C++ binaries such as Tesseract.
In addition, Iron OCR is specifically good at reading real world documents such as scans and photographs which may have digital noise or be skewed. These may throw traditional OCR libraries off the trail and provide very poor results, but Iron OCR detects these imperfections and corrects for them during the OCR process, generally giving greater than 95% OCR accuracy. more
