Re: Search a scanned PDF document for an image (signature)?
Hmmm... it may depend on how it was "signed" or how the PDF was created. Just thinking out loud here...
If the PDF was created by scanning papers that were signed previously, then the signature image would be part and parcel of the scanned image and I suspect that would be very difficult to search for. I don't think you will find cheap "signature recognition" software that could match up 'close but not exact' images - which is what multiple versions of someone's signature would be. No one ever signs exactly the same...
However, if the signature was added ("pasted" per se) as a separate image to a prior PDF file, then that separate image would represent a component of of the PDF that could in theory be searched for. In that case, every signature would be exactly the same and a search for that image could be done...
I hope that makes sense... :-/
I appreciate the feedback. These were scanned documents that were signed previously.
I suppose there must be something out there but, like you say, no signature is the same. This is not a "mission critical" task, but in the meantime I am using slow time every now and then for a needle in a haystack review of a few thousand page scanned file.
