This adjusts brightness, contrast and saturation across the pages. On old or faint scans it is often the difference between a page OCR cannot read and one it can.
Often significantly. Clean contrast between text and background is what OCR depends on most.
Sometimes. If the ink registered at all, raising contrast can bring it up. If nothing was captured, nothing can be recovered.
Only scanned images are altered. Digitally drawn text is unaffected.
These tools handle one document at a time. When the job is thousands of files, Greenbooks handles document digitization as a managed service, including bulk scanning, OCR and metadata capture, with the output loaded into DocuVenta DMS. Talk to us about volume work.
