Need to OCR a jpeg file in C# or VB (.net)

If you are simply looking to load in a JPEG image then OCR that image to extract the text then you should check out the LEADTOOLS OCR SDK. You can see the OCR Engine in action with a demo in which you can test out with your actual JPEG to see the accuracy of the engine.

Here is also a small code snippet that will show you how simple it can be to create your own OCR application to retrieve the text from the image

// Initialize the OCR engine
ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.Advantage, false);
// Startup the engine
ocrEngine.Startup(null, null, null, @"C:\LEADTOOLS 19\Bin\Common\OcrAdvantageRuntime");
using (IOcrDocument ocrDocument = ocrEngine.DocumentManager.CreateDocument())
{
//Load image
RasterImage image = ocrEngine.RasterCodecsInstance.Load(file, 1, CodecsLoadByteOrder.Rgb, 1, -1);
//Add pages
ocrDocument.Pages.AddPages(image, 1, -1, null);
//Recognize Page
ocrDocument.Pages.Recognize(null);
//Save Text
ocrDocument.Save(outPut, Leadtools.Forms.DocumentWriters.DocumentFormat.Xls, null);
Console.WriteLine("Done");
Console.ReadLine();
}

If you have Microsoft Office you can use the Microsoft Office Document Imaging (MODI) Component to achieve your goal of OCR
