You’re at a museum doing research for a paper you need to write. To capture the useful information in the labels underneath the artworks, you take photos of them using the camera on your phone.
That saves you time on the spot, but when you get home, you still have to go through each photo and manually type the text on your computer—a task you neither enjoy nor have the time for. Worst of all are the typos you keep making in the process.
What’s a student to do? If you’re looking for a way to make captured information instantly usable, keep reading.
Eliminate manual data entry
You can free yourself from having to type information contained in scans and images by turning them into machine-readable text.
Using technology that recognizes the characters within images and scans, you can make text from photos of handwritten notes or scans of book pages instantly usable—meaning you can select, copy, and edit the text in them.
Here’s how this technology works:
- First, it distinguishes dark from light in your document, recognizing all that’s dark as characters to be read and all that’s light as background.
- Second, it processes the characters, distinguishing them as either numbers or letters.
- Third, it uses pattern recognition and/or feature detection to identify each character.
- Finally, it converts each character identified into American Standard Code for Information Interchange (ASCII) code, the most common format for text files in computers, to make it usable.
That’s it. The process—known as optical character recognition (OCR)—takes just a few seconds.
Benefits of OCR
Performing optical character recognition on images and scans allows you to:
- Turn scans into editable PDFs so you can work with content without having to retype it
- Make files searchable so you can find the information you need.
- Edit the content of files so you can make updates and corrections
- Ditch paper so you can save space and preserve documents for longer
- Enable text-to-speech conversion so you can make documents accessible to the blind and the visually impaired
PDFpen’s optical character recognition
PDFpen uses OmniPage, one of the world’s most accurate OCR engines according to TechRadar.
PDFpen’s OCR technology enables you to:
- Batch OCR, i.e., perform optical character recognition on multiple files to save time
- OCR documents in languages other than English — see the full list here — so you can make text searchable in French, Portuguese, Danish, German, and more.
