Hello,

I want to train numbers and letters. They are point to point. I've attached a sample.

I have two questions that I would be appreciate if you answer these questions.

How can I use your code to get the best results?

If possible, give a brief description about your code?

Yours sincerely

Hello Tandis,

If you want to read your Images, at first you need to create OCR file. Once it is done, you can read your images.

Pls check example in NI VISION,

C:\Program Files (x86)\National Instruments\LabVIEW 2014\examples\Vision\OCR\OCR.vi

Sample VI as per your image:

Dear Munna

Thank you very much for your reply. But my problem isn't solved. I understand the ocr code and it's functionality. I can't understand the training code,well!!

To use the training code, I would try the following two way, but i can"t get result.

1- When the image is called, and the system detects an area around each character that is marked in red (picture 1) , I put the actual amount all of characters in (CORRECT TEXT) and push ok button. But in The (OCR RESULTS) , No results not shown (picture 2)

2-  When the image is called, and the system detects an area around each character that is marked in red (picture 1), I would choose an area around a character  that is marked in green, then i put the  actual amount of character in (CORRECT TEXT) and push ok button (picture 3,4). 

In this way, I see my teached character in (OCR RESULTS) and (TEACHED CHARACTERS)(picture 4). But after the way, the code cannot recognize red zone around the characters.( picture 5)
