The first and the last item are in the right position.

1. An OCR (Optical Character Recognition) system enables you to input printed documents into your computer automatically via a scanner.

FineReader is an omnifont optical text recognition system. It means that the system recognizes texts in practically any font without prior training. The process of document input can be divided into two stages:

2. The principles of IPA (Integrity, Purposefulness, Adaptivity):

· Integrity – the object of recognition is described as a single entity by a set of basic elements and their interrelations.

· Purposefulness – recognition is a process of generation and purposeful verification of hypotheses.

· Adaptivity – the system ability to learn and be trained.

3. Let’s take a closer look at the second of two mentioned above stages.

FineReader OCR image processing involves analyzing the image file transmitted by the scanner (layout analysis) and recognizing each character.

4. These three principles determine the systems behavior.
The system generates a hypothesis about object of recognition and then tries to find all the structural elements and their interrelations step by step. Then the program adapts itself to the text – tunes itself – using the positive experience gained from the first confidently recognized characters. Purposeful searching and using context enable the system to recognize even torn and distorted characters.

5. The final result is the recognized text you see in the FineReader Text window, a text you can edit save in any convenient format.

6. These two stages are:

Scanning. During the first stage the scanner acts as the «eye» of your computer; it looks at the image and transfers it into the computer.

Recognition. During the second stage FineRider performs the OCR image processing.
