OCR in .Net Core

Jayant Tripathy

My requirement is to develop an application of OCR using .Net Core. Whether it is image/PDF when it uploads it into server it read the content and provide the result.

I go through multiple search and Found "Lead Tools" in Nuget that may help for the requirement. If anyone has already done on this regard please notify me.

Thanks Waiting for valuable replay.

You can use LEADTOOLS OCR feature in your application as simple as this:
using(IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD, false))
{
//Startup the LEADTOOLS OCR Engine
ocrEngine.Startup(null, null, null, null);
//Run the AutoRecognizeManager and specify PDF format
ocrEngine.AutoRecognizeManager.Run(inputFilePath, outputFilePath, DocumentFormat.Pdf, null, null);
Console.WriteLine($"OCR output saved to { outputFilePath }");
}
The following post contains sample project and a video Tutorial that shows how to create a .NET Core application:

Also they have cloud services that you can use instead of creating your own application.

You could try Tesseract: https://www.c-sharpcorner.com/article/ocr-using-tesseract-in-C-Sharp/

Which now supports .NET Core: https://github.com/charlesw/tesseract/issues/298
