We present a Pattern Matching Based Compression (PMBC) system which compresses scanned documents into PostScript format. The output of a PMBC system is a pattern library, or font, and a series of pattern indices and positions. PMBC represents scanned documents in the same way that word processing programs represent their output pages. We explore various PostScript representations of this output...

Electronic material (e-documents, e-books, on line resources, etc.) represents an essential tool for continuous learning for print-impaired people, provided it is well-structured. To obtain accessible and usable e-content, specific requirements should be applied from the early beginning or used when adapting existing electronic formats. In this paper we present a method, and a first associated ...

Photographs must be converted to halftone format when they are prepared for print reproduction. To faithfully reproduce an image using halftone dots, the proper resolution must be chosen to match the end use of the printed product as well as the attributes of the process and materials that will be used to reproduce the image. One of the important considerations when making a halftone is screen ...

Learning more about when and why medical students, faculty, and clinical staff use e-books, as opposed to print books, is an expanding area of research for health sciences librarians. Several studies have highlighted the heavy use of health sciences titles in campus e-book collections [1–5] and the book format preferences of medical and other health sciences students [2, 6, 7]. A recent case st...

We propose a new high capacity color barcode, named HCC2D (High Capacity Colored 2-Dimensional), which use colors to increase the barcode data density. The introduction and recognition of colored modules poses some new and non-trivial computer vision challenges, such as handling the color distortions introduced by the hardware equipment that realizes the Print&Scan process. We developed a proto...

Two key obstacles have prevented the publication of a comprehensive collection or archive based on the textual iconography of the Quixote: 1) the rarity of and difficult access to the materials, and 2) the technical and financial difficulties in compiling and disseminating such an archive in print format. The advent of hypertext, digital libraries, and the Internet, among other technological fa...

With the introduction of the Cumulative Index to Nursing and Allied Health Literature (CINAHL) on CD-ROM, research was initiated to compare coverage of nursing journals by CINAHL and MEDLINE in this format, expanding on previous comparison of these databases in print and online. The study assessed search results for eight topics in 1989 and 1990 citations in both databases, each produced by Sil...
