Printer Mechanism-Level Data Hiding for Halftone Documents
∗ Research partially supported by the National Science Foundation under Grant No. 0524540-CNS Abstract Techniques to embed information in printed documents have lately attracted considerable attention due to their various applications such as copyright protection and forensic document examination. One method is to embed data in the halftone portions of a document during the printing process. Th...
متن کاملPrinting Multistrain Bacterial Patterns with a Piezoelectric Inkjet Printer
Many studies involving interacting microorganisms would benefit from simple devices able to deposit cells in precisely defined patterns. We describe an inexpensive bacterial piezoelectric inkjet printer (adapted from the design of the POSaM oligonucleotide microarrayer) that can be used to "print out" different strains of bacteria or chemicals in small droplets onto a flat surface at high resol...
متن کاملPrinter Mechanism-Level Data Information Embedding and Extraction for Halftone Documents – New Results
∗ Research partially supported by the National Science Foundation under Grant No. 0524540-CNS Abstract Embedded information in printed documents can be used for a number of applications such as authentication of document content, proof of ownership, and identification of the printer that produced documents. One approach is to embed information in the halftone portions at the printer mechanism-l...
متن کاملAn Algebraical Model for Gray Level Images
Vasile PATRASCU Department of Informatics Technology, Romanian Air Transport (TAROM) e-mail: [email protected] Ioan VOICU Advanced Technologies Institute e-mail: [email protected] Abstract: In this paper we propose a new algebraical model for the gray level images. It can be used for digital image processing. The model adresses to those images which are generated in improper light conditions (...
متن کاملColor Shift of Printing with Hybrid Halftone Images for Overlay Misalignment
Color printing proceeds with multiple halftone separations overlay. Because of separation overlay misalignment in printing, the percentage of different primary color combination may vary and it will result in color shift. In traditional printing procedure with AM halftone, every separation has different screening angle to make the superposition pattern in a random style, which will reduce the c...
