Optical Character Recognition: Definition, Uses, Benefits and More

Suppose you’re looking for a business solution where you can automate data and extract data from written or printed text from a scanned image or document. In that case, you should opt for the OCR [Optical Character Recognition] technology. 

This technology can also transform the text into a machine-readable form to be utilized for data processing, such as searching or editing.

OCR, or Optical Character Recognition, is a globally-recognized procedure that adheres to image processing algorithms for converting any text image in a scanned document into decipherable text format. 

For instance, when having a scanned document of a receipt or form, the laptop or computer saves the document as an image file.

In that case, you won't be able to search, edit, or count the words in the file even after using any text editor. This is where OCR software comes to aid. The best OCR systems convert the scanned image file into a machine-readable text document with all content stored and preserved as text data.

Optical Character Recognition (OCR): What Is It Exactly?

An OCR or optical character recognition software is a set of techniques and technologies leveraged to recognize characters and extract text automatically from unorganized files like physical printed documents, screenshots, and document images, with a high level of accuracy powered by a computerized vision and AI.

Types of OCR Technologies available in the Market

The market has various OCR technologies, which can be further categorized depending on what they capture. The various types include the following:

OCR (Optical Character Recognition):

OCR systems recognize characters or text printed depending on the current internal database.

OWR (Optical Word Recognition):

Optical Word Recognition or OWR, is a bit different than OCR because it targets all the typewritten text and one word at a time. This method is utilized for all those languages, which separates all the words with spacing.

Also known as OCR, this software focuses on one particular word at a time and works on the text on printed documents. This system is used for languages that split any word with spacing.

ICR (Intelligent Character Recognition):

ICR, or intelligent character recognition, leverages data capture tools to read and recognize text printed or cursive text. It is one of the advanced methods that leverage the power of AI and ML (machine learning) to analyze the multiple components of a text, including lines, loops, curves, etc.

OMR (Optical Mark Recognition):

This method ensures pattern recognition and analyzes logos, marks, symbols, and watermarks on any paper document.

How does Optical Character Recognition work?

An OCR software comprises both software and hardware. The reason behind using this system is to read and recognize the content present in a physical document and convert the text within into machine-readable text format for seamless data entry workflows.

OCR, popularly called text recognition, was a hit in the 90s as most companies used it to convert their physical documents and records into digital format. Since then, there has been a significant improvement in the reliability and precision of OCR technology - with simultaneous growth in the demand for wider application.

The applications or operations of modern OCR technology can be classified into four stages:

Stage 1: The Image Acquisition

In this step, a scanner is used for reading the physical paper documents, and then they get converted into scanned images. The document gets rendered in the black-and-white method. After that, the document differentiates the characters [Darker] and the background [Brighter areas of each other.

Stage 2: The Pre-Processing Work 

Under this step, the OCR software will correct all the errors or mistakes through techniques such as normalization, zoning, binarization and de-skewing. This will help enhance the accuracy of all the scanned images. 

Stage 3: The Text Recognition

AI or Artificial Intelligence tools are utilized for detecting all the actual characters from the scanned document or image. This is done through two primary algorithms, feature extraction and pattern matching.

Stage 4: The Post-Processing 

The Optical Character Recognition software will convert all the extracted data into electronic files or documents. The advanced OCR software can even compare the extracted data with the library or glossary of characters, which will help ensure maximum accuracy. 

Stage 5: Implement OCR Technology in your Industry

No matter which OCR software you opt for, it will only follow the four steps mentioned above to convert a historical document or a paper into digital files. The software will ensure that the converted file is updated, indexed and saved. 

After that, the OCR program will get implemented for all business and commercial purposes. Among the most widely used applications of OCR programs is word processing. Individuals or enterprises can scan printed paper files to convert them into searchable, shareable, and editable versions.

Industries that deal with massive amounts of paperwork will surely benefit from this technology. For example, OCR software facilitates seamless accessibility by adding signed legal documents or contracts (let’s say finance documentation) into a secure database.

Moreover, retailers can easily identify their products by using serial numbers. In warehouses and retail stores, product barcodes can be scanned through robots. These robots can also conduct OCR (optical character recognition) to obtain serial numbers and use the data to manage inventory later.

Lastly, OCR transforms historical documents into searchable and machine-readable PDFs. This is especially beneficial for retaining periodicals, old paper records, and other documents in industries like insurance, medicine, etc.

Use Cases of Optical Character Recognition (OCR)

The most common and popular use cases of the OCR technology are the following:
