What is OCR? OCR Technical Features

What is OCR?

Suppose you want to digitize a magazine article or print a contract. You may need to take the time to re-enter and correct the error. Alternatively, you can use scanners (or digital cameras) and optical character recognition software to convert all materials into digital formats in just a few minutes.

What is OCR?

Optical character recognition (OCR) is a technology that allows you to convert different documents, such as converting images taken by Scanning paper documents, PDF files, or digital cameras into editable documents.

Suppose you have obtained a paper file, such as a magazine, a color page, or a PDF contract from your partner. Obviously, a scanner alone is not enough to convert these documents into editable documents, that is, Microsoft Word. What a scanner can do is create an image or a black-and-white or colored image document. To extract text and data from Scanned documents, PDF files, or digital images, you need OCR software to identify information on images, from words to sentences, and then to the entire editable document.

What technology is behind OCR?

The mechanism for human recognition of objects still needs to be explored, but the three basic principles have been mastered by scientists, the integrity, the purposefulness and adaptability) (IPA *). This is also the principle that the core technology of abbyy finereader is imitated and followed.

Let's take a look at how finereader OCR identifies a document. First, this program analyzes the structure of the document image. It divides documents into some basic elements, such as document blocks, tables, and images. These lines are separated into words and then into letters. Once the letter has been identified, the program will compare it with some template images. He will perform a lot of logical analysis on what the letter is. Based on these logics, the program analyzes words and letters. After analyzing a large number of possibilities, this program will finally judge and present the documents for recognition.

In addition, abbyy finereader provides dictionaries in 36 languages. This will help you analyze document elements at the second level. With the support of dictionaries, you can perform more precise analysis and document recognition to reduce the validation of future recognition results.

Basic Principles of finereader OCR

The most advanced recognition system, such as abbyy finereader OCR, imitates manual recognition. At the core, these systems follow three fundamental principles: integration, purposefulness, and adaptability ). Actually, observing an object must take into account the internal correlation of the object. The purpose is that the expression of the index data has a certain target. Adaptability means that the program must have self-learning ability.

Everyone does not need to become an OCR expert and learn about IPA in OCR. These rules only provide the maximum flexibility and intelligence of the class, and the maximum possibility of manual identification of the template.

After years of research, abbyy can apply IPA principles to OCR products.

Recognize digital photos

The pictures and scanned documents taken by a digital camera are different from those in PDF documents. They are often distorted and dimmed, making it difficult for OCR to identify documents correctly. The latest version of abbyy finereader supports adaptive identification, especially for processing digital images. It provides a series of features to improve image quality so that you can fully use your digital devices.

What benefits does OCR bring to you.

Using abbyy finereader, the recognized documents are like the original documents. Advanced and powerful OCR software will help you save a lot of time and energy, saving you from creating and processing different documents. With abbyy finereader, you can scan documents for future editing and sharing with your colleagues. You can extract information from books and magazines, and provide materials and materials for your own research without re-typing. With digital cameras and OCR, you can capture information on bulletin boards, posters, and timelines to meet your needs. At the same time, you can capture newspaper and book information, even when there is no scanner at hand. You can also use OCR to create searchable PDF documents.

The entire process from initial paper documents, images, PDF files, and data conversion takes only one minute. The recognition results are almost the same as the original ones.

How to Use OCR software?

It is very easy to use abbyy finereader OCR. The process consists of three steps: open or scan the document, identify it, and save it to the format you need (Doc, RTF, xls, PDF, HTML, TXT and so on .) you can also directly output data to office applications, such as Microsoft Word, Excel or Adobe Acrobat.

In addition, the latest version of abbyy finereader supports the automatic task mode, which will be of great help to your daily work. With this function, the recognition task runs automatically without manual intervention. More abbyy finereader Mac version for free download!
