How is OCR used to categorize documents?

Often it took hours to find documents, categorize them, and sort them into groups. All this data is now captured using OCR data capture. Optical character recognition accurately identifies and classifies the various scanned documents, such as an image of an ID.

How to know if a PDF contains only images or has been OCR?

Various PDF tools can tell you if there’s text. Some are available as COM controls, and maybe even native .NET ones. Open the document in acrobat. Go to File -> Properties.
