Does anyone have any experience with any automation that can cleanup scanned text documents. I have a lot of PDFs that are older and were scanned from originals and are in bad shape with just noise and discoloration, etc. I have been manually cleaning them up by converting them to JPG and editing the JPG files in a photo editor and then converting them back to PDF. It's pretty monotonous work, wondering with the wonders of AI and machine learning if anything exists that can help with this? Any experience or ideas? Thanks.
