I'm using Tesseract and I want to develop an app that is able to recognize a sequence of characters. I had good results but not exellent.
The characters sequence I want to read has always a specific pattern, let's say:
number number number char char - (e.g.: 123AB)
Is there a way to "tell" the ocr engine that the structure is always fixed, in order to improve the results of the recognition?
Thank you in advance.

Try bazaar matching pattern in Tesseract:
\d\d\d\c\c
You can use the "tessedit_char_whitelist" parameter
