In one embodiment, an image of an original document and a marked document are received. The original document was printed using a print device which caused a print defect in the hardcopy print. Methods for identifying the print defect in the difference image are provided herein. The identified print defect is removed from the difference image. The difference image retains the user-applied markings once the print defects have been identified and removed. The user markings can then be provided to a storage device for subsequent retrieval and added into the image of the original document to generate an image of a new marked document containing the user markings without the defect. Various embodiments are disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Preserving user applied markings made to a hardcopy original document","description":"What is disclosed is a novel system and method for identifying and removing print defects from an original document such that user markings applied to the hardcopy originally can be more readily ident","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8488181","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
