Object (Optical) Character Recognition (OCR) is a technology that converts any kind of images containing written or printed text into a machine-readable format. Whether it is automatic text extraction, document conversion to PDF or translation with a prone camera, character recognition apps stand behind it. This “hidden” technology is very widespread, powering many renowned apps such as Adobe Acrobat, Office Lens, Google Docs, Google Translate etc.
As the business world goes digital, OCR has become a first step to digital transformation. The companies’ ability to fully complete the digital transformation journey highly depends on the way they operate. The current trend towards automation of manual routine work and enterprise-grade makes Object Character Recognition systems a must-have for keeping pace with today’s innovative world.
Object Character Recognition and How it Works
OCR software analyzes an image for light and dark areas, identifying light areas as background and dark areas as written characters. Then it converts the text inside the image in a machine-readable text. This operation includes such processes as image acquisition, preprocessing, segmentation, feature extraction, classification, and post-processing.
- Image acquisition
Scanning a physical document and uploading its digital copy into the OCR system.
The process refers to the training data, that are used in the OCR model. Preprocessing incorporates thresholding (transforming of a physical document into a binary image), normalization, and noise reduction.
Segmentation technique is aimed at breaking a whole image into subparts, enabling the character recognition apps to easily process the document.
- Feature Extraction
The Feature Extraction is used for extracting the most relevant information from the text image, enabling the software to recognize the characters in the text.
The classification stage allows to identify the character categories.
Post-processing is the process aimed at reduction of noise and errors in the converted document.
OCR, ICR, and IWR
As Document Management has become an important component of every business undergoing digitalization, it is important to differentiate clearly between such terms as Optical Character Recognition (OCR), Intelligent Character Recognition (ICR), and Intelligent Word Recognition (IWR) .
Intelligent Character Recognition (ICR) refers to a recognition engine that can analyze not only printed but also handwritten texts and process various fonts, patterns, and numbers.
Intelligent Word Recognition (IWR) is a more complex technology that, rather than working with individual characters in both printed and handwritten text, can recognize entire words, including unconstrained handwritten text and fonts.
Most popular OCR-driven Solutions
Mobile document scanning— an OCR-powered mobile application allows users to take a photo of a document and convert it to text data. This new feature of the character recognition apps makes smartphones more attractive for users, who no longer have to get the physical text scanned with the use of an additional device as was the case with earlier, less technologically sophisticated, systems.
Parking validation— City governments apply mobile character recognition apps to automatically validate that cars are parked legally according to state regulations. OCR embedded mobile devices allow to scan license plates of vehicles and check against an online database whether relevant regulations are observed.
Document Management— Document Management (DM) refers to automated workflow of company documents. A key aspect of a DM application is its ability to search and edit vast document flow. Applying OCR solutions facilitates the process of searching and sharing also of corporate information.

With character recognition applications Supply Chain companies gain more value due to more accurate data capture by speeding operational processes and decreasing the cost of processing packages, mailed letters, parcel registration, tracking, and delivery. Moreover, an OCR-driven software instantly recognizes and captures the text on the packaging, sending it directly to back-end systems for shipping validation.
Business Benefits of Character Recognition Apps
OCR engine processed data are transferred in text searchable formats, such asdoc, rtf, txt, pdf etc. Moreover, the required information can be internally found using a computer command Ctrl+F/Command+F.
Once a paper document is digitized with an character recognition app, it can be easily amended with a word processor, such as Microsoft Word or Google Docs.
Digital text data, both current and historical, are automatically stored in electronic libraries and storages.
Digital storages of electronic documents can be easily accessed by locally distributed users.
OCR-powered solutions also embrace translational capabilities. An OCR engine is used for extracting the text from a scanned document and then translating it to a different language.
Digital back-ups are cost-effective, and potentially, can be done an infinite number of times. Instead of maintaining costly duplicates and triplicates in paper form, object recognition software automatically creates OCR backups.
Next Generation of Character Recognition Apps
As the world becomes more tech-paced, OCR technologies do not stay still and keep track of innovations. The advanced OCR system is powered with Artificial Intelligence (AI). With its Deep Learning (DL) capabilities, AI enables OCR software to do more than just recognize text, it can derive meaning from it.
According to IDC, by 2021, global spending on AI systems will reach $57.6 billion.
Traditional OCR systems are template-based. The accuracy of converted documents highly depends on the quality of the input data that must fit the OCR framework. For the identification of entities in a document, OCR engines use templates. However, templates cannot handle possible complexities, such as combinations of printed and handwritten text, variations in formats and tabular data. Therefore, unidentified elements as well as possible errors have to be processed manually.
An alternative to the traditional character recognition app is AI-powered OCR software. Based on DL techniques, AI enables object recognition technology to parse, assign meaning and content structure to the provided text beyond just extracting it. Moreover, the overall accuracy of the software is improved, as the system automatically learns representations from a large amount of data, such as images, video or text, without human involvement. As a result, a DL-driven OCR system can work with thousands of document variations, reducing mistakes that the traditional OCR system may make.
According to Forbes, the future of Optical Character Recognition is Deep Learning.
“With deep-learning-driven OCR, the company that scans insurance contracts gets more than just digital versions of their paper documents. They get instant visibility into the meaning of the text in those documents, thus unlocking billions of dollars worth of insights and saved time.”Forbes
AI-driven Object Character Recognition
Artificial Intelligence, abbreviated as AI, is a branch of computer science that creates a system able to perform human-like tasks, such as speech and text recognition and problem solving. Using AI-powered technologies, OCR applications can accomplish specific tasks by analyzing huge amounts of data and recognizing in them recurrent patterns.
AI is mostly used at data preprocessing stage for the identification of relevant sections requiring extraction and classifying text data before extraction. Additionally AI enables the Object Character Recognition system to derive meaning from the current and historical data, flagging possible errors, exceptions, as well as fraudulent activity.
