How OCR form processing works

Optical Character Recognition (OCR) is a widely used technology that converts handwritten, typed, or scanned text from images and text within pixels of the scanned images into machine-readable text. This capability makes OCR an intelligent tool for processing forms and other documents.

Explanation of OCR technology

OCR form and document processing refers to the application of OCR technology to extract data from forms. These forms can include contracts, surveys, applications, medical records, etc. This process automates data extraction and document processing, improving efficiency and accuracy in handling diverse types of documents.

Before understanding the OCR form processing workflow, learning the different types of forms involved is necessary. Let’s break it down.

Type of forms: structures and unstructured

Structured forms: Structured forms consist of clearly defined text blocks with fields that consistently appear on each page in the same locations. The only variation lies in the information entered into each field. OCR technology is highly effective with structured forms because the data remains in fixed positions on each page, allowing for accurate and efficient data extraction.

Unstructured forms: An unstructured form is a document that lacks a predefined layout or consistent format. Unlike structured forms with clearly defined fields and sections, unstructured forms can contain information presented in various ways, making data extraction more challenging. Examples of unstructured forms include emails, letters, reports, PDFs, forms, and free-text fields within documents.

Semi-structured forms: Semi-structured forms present a unique challenge because the location of identifiers and checkboxes can vary, as do the data fields. This variability in key poses a problem for template-based OCR software, for example, which may capture incorrect data if it appears in unexpected locations on the page. As a result, processing semi-structured forms requires more advanced OCR solutions capable of adapting to these inconsistencies.

Different types of forms impact OCR software accuracy differently. Structured forms with consistent layouts deliver high accuracy, while unstructured forms like emails pose challenges. Semi-structured forms, with some consistency but variable elements, require adaptable OCR solutions.

When choosing any OCR solution, consider form and image types, advanced features of software, AI and Machine Learning capabilities, and integration to ensure efficient document and image handling. Intelligent OCRs that are powered with AI can handle all kinds of structured and unstructured with a very high rate of accuracy.

Process of extracting data from forms

Let’s take a look at the steps involved in OCR form processing:

• Scanning or pre-processing: This step involves scanning physical documents or receiving digital documents. If the documents are already scanned, pre-processing may include tasks such as image enhancement to improve quality and clarity, noise reduction, and skew correction to ensure the document is properly aligned.
• Format and content detection: Once the document is prepared, the OCR software needs to identify the format and layout of the document. This involves detecting text blocks, fields, tables, and other structural components.
  For structured forms, this step is relatively straightforward. However, for unstructured or semi-structured forms, this step can be more challenging due to the lack of a predefined layout.
• Character recognition: In OCR form processing, detecting lines and visual features is crucial for accurate table extraction. Basic character recognition isn’t enough, making table extraction a challenge. Computer vision and machine learning algorithms add context to the extracted data.
• Post-processing: Once the characters are recognized, post-processing steps improve the accuracy and usability of the extracted data. Post-processing may also involve data formatting and integration into databases or other systems for further analysis or processing.
• Output: The extracted data is organized into structured formats such as tables, spreadsheets, or databases. The digital data is stored in a central repository or cloud storage of the organization. Authorized users can access the digitized and structured data for various purposes.

Role of OCR in automating data entry

OCR is necessary for automating data entry. It converts scanned documents, PDFs, and images into editable text, reducing the need for manual data entry.

Challenges and solutions

Here are the most common challenges in OCR form processing:

• Accuracy:  Structured forms have a predefined format- for instance, tax forms or surveys. While OCR is effective with these forms, it’s never entirely accurate. In contrast, semi-structured forms, like invoices or contracts, have a more flexible layout. OCR struggles even more with these forms, further compromising accuracy during processing.
• Formats, fonts, and handwriting: These present significant challenges for OCR software. Complex layouts, such as those with multiple columns, tables, or graphs, interfere with text recognition and segmentation. OCR works best with standard fonts and Latin alphabets, struggling with unique fonts and non-Latin scripts.
  Handwriting variability, including cursive writing and inconsistent clarity, further complicates accurate text recognition. These factors limit OCR’s effectiveness, often requiring specialized tools or manual intervention for precise results.
• Watermarks and holograms: watermarks and holograms are troublesome for OCR systems. They can hide the text below or deform it, meaning that OCR systems will face problems accurately identifying and retrieving it.
  Watermarks can create a background that will diminish text visibility, while holograms can reflect light and create different intensity levels that complicate text retrieval. That is why visual disturbances bring down OCR accuracy, which often results in extra processing time or the need for manual approval to guarantee accurate data retrieval.
• Image quality: Image quality significantly impacts the performance of OCR software. Factors such as resolution, lighting, contrast, and noise play crucial roles in the accuracy of text recognition. Low-resolution images may result in blurred or pixelated text, making it difficult for OCR systems to accurately identify characters.
  Poor lighting and contrast can obscure text details, while image noise can introduce random variations that interfere with text recognition. Consequently, poor image quality often leads to higher error rates and misrecognition in OCR processing.
• Multilingual content: Multilingual content poses a substantial challenge for OCR software. While many OCR systems are optimized for the Latin alphabet, they often struggle with non-Latin scripts such as Cyrillic, Chinese, Arabic, or Hindi. Each language has unique characters, structures, and fonts that require specialized training and algorithms.
  Additionally, documents containing multiple languages or mixed scripts can further complicate the recognition process, leading to increased errors and reduced accuracy. This limitation necessitates the use of advanced OCR systems or language-specific models to handle multilingual content effectively.
