How to Convert Handwriting to Text Accurately

Converting handwritten notes typewritten text accurately is no small task. Manual conversion could take more time than is available, while scanning into PDF will likely result in un-editable images. Have you ever wondered if there is a tool designed specifically to 'retype' this text for you? Scroll on down for an introduction to various tools designed specifically to transform handwriting to editable text. But first, let's discuss one key technology that makes handwriting-to-text possible: Optical Character Recognition (OCR)

What Is OCR?

In simple terms, OCR technology equips computers with the ability to read and interpret text from visual sources like printed material, handwritten notes and image files, just like humans do. This technology facilitates the transformation of these text-based images into digital files that can be edited.  Its uses are wide-ranging, particularly benefitting sectors such as data entry, where it significantly simplifies the digitisation and editing process for various types of physical documents like receipts, invoices, and handwritten content.

‍

How Does OCR Work?

OCR takes a scanned document, saved in an image format like PDF or JPG, and converts it into editable and searchable text. This process includes three steps:

1. Pre-processing: The software prepares the image. It aligns the text, removes noise and spots, distinguishes the text from the background, classifies text areas, and adjusts characters as needed.

2. Text Recognition: The software then matches image shapes with known text patterns or character recognition rules. If the text is handwritten, a two-scan process is used. The first identifies the writing style, and the second maps the recognized symbols to possible characters.

3. Post-processing: Lastly, the software verifies the text by comparing it against known terms or rules, enabling error corrections to ensure the accuracy of the final editable text.
   

What Are the Different Types of OCR?

To fully grasp how OCR works, it's important to understand its various forms and their abilities in document interpretation. Here are a few types:

1. Optical Character Recognition (OCR): This is the standard form of OCR that identifies printed characters in a document.

2. Intelligent Character Recognition (ICR): An advanced version of OCR, ICR can recognize handwriting from scanned documents or photos.

3. Optical Mark Recognition (OMR): Used mainly for checkboxes and filled-in circles, like those on a multiple-choice test, OMR can recognize the presence or absence of a mark in a specific location.

These OCR variations can function individually, or collectively. Some of the examples below illustrate how these technologies can intertwine to enhance their effectiveness.
