Printing technique classification for document counterfeit detection Christoph Lampert ; https://orcid.org/0000-0001-8622-7887 Mei,Lin Breuel,Thomas M The detection of counterfeit in printed documents is currently based mainly on built-in security features or on human expertise. We propose a classification system that supports non-expert users to distinguish original documents from PC-made forgeries by analyzing the printing technique used. Each letter in a document is classified using a support vector machine that has been trained to distinguish laser from inkjet printouts. A color-coded visualization helps the user to interpret the per-letter classification results IEEE 2006 info:eu-repo/semantics/conferenceObject doc-type:conferenceObject text http://purl.org/coar/resource_type/c_5794 https://research-explorer.ista.ac.at/record/3680 Lampert C, Mei L, Breuel T.
