1. Layout analysis
First, text is scanned or photographed. The software examines the page layout, separates the text from the image files, and notes the number of paragraphs and pages.
2. Character recognition
OCR breaks the text down into paragraphs, then into sentences, then into words and finally into characters such as letters, punctuation marks or numbers.
3. Pattern analysis
To identify letters, the software compares predefined patterns with the scanned characters. It uses several methods to do this:
- Feature matching, where the software analyses letters and characters based on their features (e.g. ‘H’ = two vertical lines and a shorter horizontal line).
- Pattern recognition, where OCR accesses its own database and compares letters to known characters.
4. Text creation
In the final step, OCR reassembles the recognised characters. This creates words, which are then sorted back into their place in the sentence. In addition, a grammar check in the software ensures that the sentences are correct. OCR stores the text in a document that can then be further processed. When invoices are scanned, OCR recognises this and automatically enters the correct values into the fields in the invoice file or the input mask of the incoming invoice processing software.
Better document management with OCR
OCR helps businesses in a wide range of industries with document management. It relieves companies of the burden of archiving old paper files and makes it easier to process invoices and contracts by digitising documents using optical character recognition, thus enabling automated document processing.
OCR in your business: opportunities and challenges
Using OCR in your business will improve document-centric processes and make life much easier for many departments. However, there are challenges to implementing OCR in your organisation. If you keep in mind what it means to implement OCR, your business will quickly reap the benefits.
Benefits of OCR text recognition software
It takes at least three steps out of the process by automatically analysing, formatting and storing scanned documents in a separate file. It supports document control and contract management, and is used to search large volumes of files. OCR simplifies your workflow by capturing and cataloguing documents in the digital files and folders you specify. Automatic selection of customer-related data reduces the burden on your accounting department, and the ability to post-process documents ensures that they are accurate and up-to-date.
What should your company be aware of when using OCR?
Manually entered data can contain gaps that challenge OCR coding. It is therefore important that certain requirements are met in advance:
- The document should be undamaged and easy to read
- Complex layouts and unusual fonts make text recognition with OCR difficult
- In the case of handwritten documents, consistent fonts support the accuracy of text capture
- To use the technology effectively, the OCR system must be integrated with the existing IT infrastructure
Productivity boost through software solutions with OCR
Software solutions with OCR digitise processes, capture data and generate real-time forecasts for decision-making. Applications range from invoice processing and customer relationship management (CRM) to enterprise content management (ECM) and other common or specific tasks.
Even faster processes with AI
Software solutions that also use artificial intelligence work even faster than pure OCR applications. Using programmed learning models, they automate manual tasks, analyse data and optimise communication. One example is Shareflex ECM Online. This alternative to traditional ECM systems uses the Microsoft 365 platform to provide users with complex, cloud-based business applications.
