Why Scanned PDFs Need OCR for Comparison: CatchDiff Insights
In an age where digital documents dominate, how often do you encounter a scanned PDF that leaves you scratching your head? Surprising as it may seem, over 75% of businesses still rely on scanned documents for various purposes. But here's the catch: these documents are not inherently editable or searchable, making comparisons a frustrating task. This is where OCR for PDF comparison becomes crucial.
What is OCR and Why is it Important?
Optical Character Recognition (OCR) is a technology that converts different types of documents, such as scanned paper documents or images captured by a digital camera, into editable and searchable data.
How OCR Works
OCR software analyzes the shapes of letters and words in a document, recognizing characters and converting them into machine-readable text.
1. Image Preprocessing: The scanned document is cleaned and enhanced.
2. Character Recognition: The software identifies characters and words.
3. Postprocessing: The recognized text is formatted and any errors are corrected.
Benefits of Using OCR for PDF Comparison
- Enhanced Searchability: Makes scanned documents searchable.
- Editable Content: Allows for modifications to be made easily.
- Accurate Comparisons: Ensures accurate comparisons between documents, especially when revisions are needed.
