“How do i extract specific fields text from different zoom in zoom out 
images. Previously i have cropped images by according specific region text 
using image coordinates. But problem is some images are zoom in or out and 
that changed the region coordinate. How do i handle this problem..? ”

[tesseract-ocr] Re: Not able to lift text from the attached file please help!!!

[Shobhit Kapil]

Hi, 

Thanks for the reply, i just want to elaborate what i am actually doing 
will give you a clean picture for a proper guidance!!!

I am using tesseract dll in windows and i am using the below code for 
engine and page segment mode

 private static TesseractEngine _engine;
private static TesseractEngine Engine
{
get
{
if (_engine == null || _engine.IsDisposed)
{
try
{
_engine = new 
TesseractEngine(Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location)
 
+ "\\tessdata", "eng", EngineMode.LstmOnly);
}
catch (Exception ex)
{

ex.Message.ToString();
}

}
return _engine;
}
}

then later i am initializing this engine for reading the text from image:

private string LiftText(Bitmap img)
{
string resultText = string.Empty;
try
{
TesseractEngine engine = new TesseractEngine("./tessdata", 
"eng", EngineMode.LstmOnly);
Tesseract.Page mypage = engine.Process(img, 
PageSegMode.SparseText);

resultText = mypage.GetText();
mypage.Dispose();
engine.Dispose();
}
catch (Exception ex)
{
Exceptioninfo("LiftText()", ex.StackTrace);
}

return resultText;
}

Re: [tesseract-ocr] How to train tesseract with new script?

[Soumik Ranjan Dasgupta]

If you have a font of the said script alphabet, yes, I think it is
possible.

[tesseract-ocr] Re: Training Tesseract 4 from Scratch

[Shobhit Kapil]

Hi ,

Before starting this training process i would like to know a bit about the 
process

1. i have files which are not very clear and have different sort of noises 
will the training will be helpful in such scenarios.
2. Character are not reading correctly i.e. most of the time 5 is reading 
as S and Z is reading as 2 and i as !, so will this be covered in training.

Thanks,
Shobhit
