“…Therefore, a document image database annotated with the needed ground truth information was created. As in previous works [11,17], the "Grünert" letter in the 12 pt "Courier New" normal font with a 12 pt line height was used as a template to create the ground truth document image database. This template document implements the DIN-ISO 1051 standard.…”

“…Print quality metrics include line width, raggedness and over spray, dot roundness, perimeter and the number of satellite drops [15]. Other useful quality features include the gray level co-occurrence features for the printed letter "e" [14]; and texture features based on gray level co-occurrence and local binary map histograms used in conjunction with edge roughness features that measure line edge roughness, correlation and area difference for printed document charac-ters [11]. Schulze, et al [17] have evaluated these features in the context of high-throughput document management systems.…”

The ability to discriminate between original documents and their photocopies poses a problem when conducting automated forensic examinations of large numbers of confiscated documents. This paper describes a novel frequency domain approach for printing technique and copy detection of scanned document images. Tests using a dataset consisting of 49 laser-printed, 14 inkjet-printed and 46 photocopied documents demonstrate that the approach outperforms existing spatial domain methods for image resolutions exceeding 200 dpi. An increase in classification accuracy of approximately 5% is achieved for low scan resolutions of 300 dpi and 400 dpi. In addition, the approach has the advantage of increased processing speed.

“…Ink versus laser print classification [15], ink versus laser versus photocopy classification [16], or laser versus photocopy [17] are a few examples of such methods. However, to the best of the authors' knowledge, no method has been presented so far for detecting stamps based on their printing technique features.…”

Abstract. Stamps, along with signatures, can be considered as the most widely used extrinsic security feature in paper documents. In contrast to signatures, however, for stamps little work has been done to automatically verify their authenticity. In this paper, an approach for verification of color stamps is presented. We focus on photocopied stamps as nongenuine stamps. Our previously presented stamp detection method is improved and extended to verify that the stamp is genuine and not a copy. Using a variety of features, a classifier is trained that allows successful separation between genuine stamps and copied stamps. Sensitivity and specificity of up to 95% could be obtained on a data set that is publicly available.
