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.

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.

Language packs available for Arabic, Simplified
Chinese, Traditional Chinese, Danish, English,
Finnish, French, German, Hebrew, Italian, Japanese,
Korean, Portuguese, Russian, Spanish, and Swedish

Iron OCR can be used with VB.NET to create Windows
desktop applications, server applications such as
ASP.NET websites, and even web services hosted on the
Azure framework. It can also be used to create simple
command line applications and console applications in
VB.NET.
