My system should process some images and get key data in text. Of course, the images will follow a style pattern.
Where can I start? Is there an API that can help me?

The most common and free OCR (character recognition) engine I know is the Tesseract. There are two contributions from it to . NET:
I recommend moving the images to black-and-white before using the Tesseract to read. Preferably, try to position the texts horizontally, and do not pass very small texts, which can be lost.
Another tip is the to configure a list of allowed characters for reading. Depending on how the text looks, it can swap some characters for others.

In addition to the answer you already have, you can also get help on other questions on the subject here at SOPT. Just look for OCR (Optical Character Recognition) or Tesseract.
