Did you know electronic media usage has increased the demand for digital files? Digitized documents offer distinct advantages over their physical equivalents regarding storage space and security levels. They also provide significant cost-cutting measures and are easier to use.

As optical character recognition (OCR) becomes increasingly essential for businesses and organizations, many strive to automate and streamline their digitization processes. Companies should employ invoice automation or handwriting recognition software to increase accuracy and effectiveness; others utilize artificial intelligence technologies as part of this effort.

Machine-learning-based OCR allows for accurate Image Text Recognition such as posters, street signs, product labels, and reports using machine-learning technology. Extracted text comes in different formats like texts, words, and paragraphs—you may even come across digital text scans! OCR and ML solutions have quickly become popular technologies among businesses as their use exponentially grows. Businesses across industries increasingly depend on this combination to optimize performance in their processes.

This post will highlight OCR technology and how its uses may help address business challenges.

What Is Optical Character Recognition?

Optical Character Recognition offers numerous ways of viewing, locating, and even recognizing text – in the form of labels or images – on various documents. When thinking about OCR, it can quickly come to mind that many people want to lose essential documents that take up space on their desks and may cause legal complications if lost, which is why OCR can help, and digitizing papers is vital. 

OCR Machine Learning refers to computer vision issues requiring handwritten or typewritten content from digital images to be transformed into computer-readable text for processing by your computer and then saving and modifying production using text file components of data entry programs.

Since the surge in machine training to recognize text, we have explored numerous techniques for using computer vision to solve OCR machine-learning problems. As more businesses implement machine learning software on an enterprise-wide level, robust models that adapt more readily are necessary.

How Does OCR Work?

An OCR device consists of both software and hardware. Its purpose is to analyze the content of a document and then translate the text into code utilized for data processing. Imagine this in the context of mail sorting and postal services. OCR is essential to their capability to rapidly process destination and return addresses, allowing them to sort mail quicker and more efficiently. This is accomplished in three stages:

Image Pre-processing

The first step is when the equipment (usually one that uses an optical scanner) converts the document’s physical structure to create an image, such as the image of an envelope. This step ensures the scanner will accurately reproduce the image and eliminate undesirable distortions. The image that is created is transformed into a black-and-white version. This is examined for light (background) and dark areas (characters). The OCR software can also classify images into distinct elements, such as tables, text, or image insets.

Intelligent Character Recognition

AI analyses the image’s dark parts to find characters and numbers. In general, AI targets one character (word, phrase, or chunk of text at a given time employing one of the following techniques:

  • Teams train teams to train the AI algorithm with a wide range of text and handwriting formats. The algorithm compares the letters in the image of an envelope to those it already knows to find connections.
  • New algorithms apply guidelines for specific features of characters to recognize them. Characteristics could include the number of crossed, angled, or horizontal lines and curvatures. For example, the letter “H” has two vertical lines and one horizontal line between them. The machine uses these feature identifiers to recognize the envelope’s various “H”s.
  • When the machine recognizes the characters, they’re converted into ASCII code, which is utilized for other manipulative actions.

Post-processing

In the third step, AI rectifies any errors found within the document. One option is to instruct the AI using a particular vocabulary of words to be included within the file. The AI’s output should be restricted to those specific words/formats to ensure that the interpretations do not fall beyond the scope of the lexicon.

Benefits Of OCR Technology For Businesses

Below are a few reasons your company might be considering the possibility of implementing OCR technology:

More Efficient

One significant advantage of OCR is the ability to streamline the data entry process and Text Recognition AI, saving time and reducing the possibility of making errors. OCR software extracts information from scanned documents and inserts it into databases or a spreadsheet. This significantly benefits employees who spend extensive time manually entering data, allowing them to concentrate on valuable jobs.

Access To Information Is Improved

Another advantage of OCR is its capacity to digitally scan paper documents, making them much easier to keep, search for, and browse. This is particularly beneficial when dealing with vast quantities of paper documents daily because it removes the requirement to store them physically and makes it simpler to locate the required data. Additionally, it can enhance employee decision-making and enable them to find the data they need quickly and conveniently.

Accuracy Improved

OCR technology also improves text recognition accuracy. Recently, OCR algorithms have become more sophisticated and can detect text in various languages, fonts, and documents. This precision is crucial when dealing with documents containing significant or sensitive information since it ensures that the data can be easily accessed but also precise and trustworthy.

Security Enhancing

Apart from these advantages, OCR technology can also help improve the security of private documents. Electronic storage allows firms to lower the threat of data security breaches and protect against unauthorized access. This is crucial for anyone who deals with sensitive data daily, as it will help ensure that the data they store is safe.

OCR will help companies cut paper storage, management, and processing costs. By digitizing documents, companies can reduce the need for storage facilities and save on shipping and printing costs.

Improved Customer Service

OCR is also an excellent tool for streamlining customer response times. This allows companies to answer customer inquiries faster and more accurately, increasing the customer’s satisfaction and loyalty.

Increased Assets Protection

Storing your data in physical formats like files and folders is essential, making the documents vulnerable to natural destruction, theft, or loss. After all of these documents have been changed to digital format and secured from theft, destruction, or natural disasters, you are protected from such threats. The backup of your files on the cloud or in geo-redundant data centers allows you to access these files through the DMS software from any device connected to Internet access.

In the event of cyber-attacks and other types of cyber-attacks that attempt to corrupt the stored data, additional layers of protection with sophisticated encryption can be employed to safeguard your data. Ensure that access restrictions are compatible with the regulations governing data and that your data will be secure.

Reduces Errors

Manual data entry requires large portions of processing documents that are susceptible to mistakes. Incorrect spelling, missing information, or document filing errors are all possible. Yet, OCR technology eliminates such issues for your business. Instead of manually labeling and indexing the documents, OCR converts them precisely, reducing the time spent on paperwork and helping you focus on the most critical tasks.

Supports Multiple Languages

There is plenty of information available in many languages, thanks to globalization. However, accurately capturing details in languages unfamiliar to us can seem daunting. But, OCR can simplify these jobs. AI-powered OCR technology can translate text into a variety of languages. It detects images and decides on the appropriate language, then transforms it into another based on your preferred language.

Lowers Turnaround Times

It is incredibly tiring to do the same thing over and over again. Automating your work can save time and OCR. Utilizing this innovative technology to capture data can remove manual tasks, streamline the daily management of documents, and reduce time. In addition, optical character recognition can be instrumental in filling forms. OCR recognizes the information in documents and stores it to be used later to speed up form filling or sending emails.

Top OCR Business Use Cases

OCR applications in the business sector have various possibilities. Because text recognition utilizing machine learning is more accurate than previous models of optical character recognition, the business owner can develop OCR solutions for a wide range of issues in the business. The most modern OCR technology is used for banking, security, insurance, medicine, retailers, communications, and other sectors.

The most common uses for OCR technology are examining test answers, instant translations, recognizing signs on the street (Google Street View), browsing through images (Dropbox), creating documents for AI data analysis, and many more. Security agencies frequently use OCR. The technology examines and analyzes documents like the driver’s license or ID to confirm an individual’s identity. Each time, a distinct OCR method is employed.

OCR In Healthcare

OSR instances in the health industry are linked to data management. Digitizing medical documentation and successfully extracting information from it is essential to a healthcare facility’s operations.

Utilizing the optical character recognition technique, hospitals can convert papers to a digital format faster and then save them in PDF documents that are easily searchable using keywords. Electronic medical records address one of hospitals’ biggest problems: the lack of information regarding patients’ medical conditions. 

Furthermore, OCR allows data to be retrieved from test results or certificates and then sent to hospitals’ information management systems (HIMS) for inclusion into the patient’s records, thereby creating patients’ complete medical history. Pharmaceutical systems may also use OCR. With an OCR module, these systems let users read prescriptions for medical use. Also, they can be uploaded to software to check the medication’s availability in pharmacies’ databases or utilized to regulate the selection of robots.

OCR technology is also utilized for people who have vision impairments. When you scan the text on the photo, it is possible to use the OCR system, which gives you the basis to use speech-to-text technology. The only thing you need to do is to scan the text to receive artificial speech output. For example, the Voice Speech Scanner application uses the camera on your smartphone to take an image with text and can then read the words in return.

OCR In Financial Services

Financial transactions require extensive information entry, which can take considerable time and energy to process manually. Likewise, digitizing financial documents and extracting relevant information with OCR helps make business processes more efficient. Ultimately, OCR technology helps improve customer onboarding and overall customer experience.

OCR applications in the financial and banking sectors include:

Onboarding Of The Client

Whatever financial transaction you’d like to conduct, whether it is opening an account, withdrawing money, or moving funds, first, you need to verify that you are who you say you are. OCR technology offers a completely automated process of onboarding that involves scanning the identity document; then, all the required details are extracted using OCR (e.g., date of birth, name or marriage, gender, photograph, signature, etc.) and verified with the signature. As an instance and checking it. For example, the OCR engine can check at any time if the given signature aligns with the document’s signature, proving identity.

Pay With a Scan Feature

Manual entry of payment information could be better, but it can take longer than anticipated. Scan-to-pay utilizes optical character recognition technology to capture the invoice information and process it automatically and quickly. All you need is an iPhone camera for this (for instance, you could have to snap a photograph from your credit card). OCR could also be used as additional security for making transactions. Most often, cardholders store details in applications without inputting the card’s number or other information each time. 

Receipt Acknowledgment

OCR lets you automate data extraction from receipts to facilitate analysis, accounting, or archive analysis. It is integrated into financial assistant applications, including money-tracking components, to automate data entry for expenses and expense categories. Expensify is a prime instance of such a program.

One of the biggest obstacles to accuracy in receipt recognition by OCR is the wide range of variability and frequently poor quality of receipts. When this happens, rules-based approaches will not work, and that’s the point where optical character recognition using deep learning can help. Deep learning’s approach to OCR lets the system learn from the data received and improve. This technique allows an algorithm to recognize areas of significance in images that likely include text and remove irrelevant data like background.

Processing Of Loans

OCR and Machine Learning Text Recognition can speed up mortgage and loan application processing by as much as 70 percent. Automating data entry makes reviewing applications and approving or denying them much quicker and more efficient for businesses. AI algorithms can analyze the necessary information from an application to decide if it should be accepted or not according to the bank’s guidelines.

OCR applications in finance aren’t restricted to these examples. OCR technology is also used to read other financial documents, such as invoices, contracts, bills, and financial reports.

OCR In Retail

Utilizing OCR coupled with machine learning, retailers will rapidly improve internal processes within their business and enhance customer experience by making the most of the available data. For example, they get valuable insight from purchase order data to design more efficient advertising campaigns and promotions and better manage prices. When they convert receipts and invoices to digital formats and then integrate the data into accounting systems, businesses in the retail industry can streamline the accounting process.

Implementing OCR is an excellent method to manage the massive demands of retail employees. By automating information entry and data extraction, workers need to confirm to get the best outcomes manually. Examples of the use of OCR in retail are more comprehensive than those mentioned above. 

OCR’s text recognition capabilities could address specific issues for retail businesses. In particular, it benefits wine retailers that offer many different products. Through OCR-based recognition for wine labels, it is possible to take an image of the wine label and obtain product information like descriptions, reviews, and other information. For them to make the best decision.

OCR In Security And Law Enforcement

Nearly every industry can make use of OCR to enhance security strategies. Organizations can develop advanced authentication and verification methods using OCR supported with machine learning. In general, manual comparators that include personal information and selfies are employed to confirm the authenticity of the ID provided by the user. OCR eliminates these manually-based efforts by scanning ID cards, driver’s licenses, passports, and other documents and confirming their authenticity compared to information stored in the database.

In this scenario, the OCR engine must first identify the document type. If, for instance, an individual chooses to authenticate using a driver’s license, then the file they upload to the system has to be in that document’s format. The system will then examine and analyze uploaded documents to gather relevant information.

As documents of the exact nature may differ in style based on the nation and state of origin, a system must be able to locate and collect the required information from any variation. Deep learning algorithms can help the OCR system understand the relation between different text blocks. They also allow for combining semantically linked chunks of text to discover pertinent information such as names and dates of birth.

Also, it is essential to note that security-based authentication OCR software must have security features that prevent attempts to spoof when scanning documents. Anti-spoofing strategies can assist in the detection of false ID scans and illegal attempts.

Limitations Of OCR Technology And Their Solutions

Optical character recognition (OCR) is a trendy technology, but it does have some drawbacks, mainly when we speak about traditional systems for AI Text Recognition. Combining OCR with deep learning and computer vision enhances the accuracy of OCR for many situations. However, it’s essential to realize that it’s not possible to get 100% performance and that more software is required to boost the results.

The main limitations in optical technology for character recognition include these:

Lower The Quality Of Image Resulting In Lower Quality Of OCR Output

The most common OCR mistakes include misreading letters and letters that need to be more readable or mixing text in adjacent columns. Common ways to normalize an image involve moving and aligning the image, removing blur, and applying filters. You can also remove items that do not contain character elements (like tables and separator lines).

Complex Image Background

Small lines or sharp edges that compose the background could be read as characters, which can alter the result of recognizing text. To overcome the issue of noise-related presence, including lines, dots, or stains. In the background, modern OCR techniques employ computer vision algorithms trained using augmented datasets.

OCR Performs Better When Printed Text Than Handwritten

Handwritten fonts come in a variety of different variations. This can make the process of recognizing text. The software team must develop the OCR model with advanced algorithms for deep learning and computer vision systems to recognize handwriting. The high-quality dataset used to train the model is a factor that affects the accuracy and speed with which results are produced. It’s best to utilize smaller amounts of data, but only the most useful ones.

Trends In OCR Technology

With the development of AI and machine learning, we’ll likely change the role of OCR software. Instead of being just scanners, OCR tools may grow to become analytical tools or something more substantial.
