Have you ever needed to digitize a printed paper document, archival scan or screenshot containing critical text, only to be blocked by the frustrating realization that the words trapped inside each image remain inaccessible for easy searching, editing or extraction?
Fortunately, optical character recognition (OCR) technology provides the key to unlocking this text, serving as an invaluable asset for digitizing personal documents or streamlining enterprise content workflows.
OCR innovations have progressed tremendously in accuracy and speed over the past decade. Global adoption is accelerating as well, with the worldwide OCR market projected to reach $13.8 billion by 2028. OCR is now built into leading document processing apps, available via convenient cloud APIs, and empowered by AI advancements.
In this guide, we’ll unpack 7 flexible tactics you can implement to liberate text from images using today’s most capable OCR solutions – no tedious retyping required!
OCR Quickly Demystified
OCR software automates the conversion of typed, handwritten or printed text within image or document files into digital text that can be effortlessly edited, formatted, searched and shared.
The OCR process typically involves three key phases:
- Text Detection – Identify words in appropriate images and isolate them from other graphical elements
- Character Recognition – Machine learning algorithms determine letter composition of detected text
- Output Generation – Structured editable text gets exported in desired file formats retaining much of original font and layout attributes
Common export format options provided by OCR tools include:
- Searchable PDFs – Retains full document formatting with selectable text behind images
- Machine-readable DOCX, XLSX and PPTX files
- Flowing ebook or HTML files
- Structured CSV/JSON data
- Audio narrated MP3/WAV versions
- Simple TXT/RTF plain text
Now let’s explore 7 adaptable OCR techniques to unlock the text imprisoned inside your images!
