Tessnet2 using Tesseract Engine - Why is it giving very bad results?

I am trying to use Tessnet2 using Tesseract engine in C #. For many of the test images I pass to Tessnet2, the result is very poor and almost nothing happens.

This is my code in a C # console project, Program.cs class:

 static void Main(string[] args)
    {
        try
        {
        Bitmap image = new Bitmap(@"C:\Users\hp\Desktop\eurotext.tif");
        var ocr = new Tesseract();

        //when I tried to add the SetVariable(...), it didn't change the output much

        ocr.Init(@"C:\Program Files (x86)\Tesseract-OCR", "eng", true);

        var result = ocr.DoOCR(image, Rectangle.Empty);
        foreach (Word word in result)
            Console.WriteLine("{0} : {1}", word.Confidence, word.Text);

        Console.ReadLine();
    }
    catch (Exception exception)
    {
        Console.WriteLine("Error");
    }
}

      

        
        
        
      

    

For example, this is a sample (300 dpi large binary) test image "eurotext.tif":

And this is the Tessnet2 result for this image:

I am using this site to learn how to use Tessnet2: https://code.msdn.microsoft.com/windowsdesktop/How-to-use-Tessnet2-library-716be12f

I used this site to try and use the SetVariable (...) function correctly to get it to do what I want, but with no luck and not much different from the output: http://www.sk-spell.sk.cx / tesseract-ocr-en

I found Tesseract rules to reduce engine error: http://code.google.com/p/tesseract-ocr/wiki/ImproveQuality

• it says, "Tesseract works best with text using a DPI of at least 300 dpi." This sample image is 300 dpi

• this sample image is binary as well, which should give a better result as many people have talked about on various sites.

I've looked everywhere for a solution that can improve accuracy and I've found many posts and people with similar problems but no working solution.

What is the cause of this problem? How can I solve it?

I'm getting started on this thread, so please bear with me if the solution is too trivial.

Thank!
