In this paper two intensive problems faced during software application’s analysis and development process arose by the software industry are briefly conversed i.e. identification of fault proneness and increase in rate of variability in the source code of traditional and product line applications. To contribute in the field of software application analysis and development, and to mitigate the a...

A paper-based interface for browsing video is proposed. A paper document shows key frames selected from a video, a transcript for the parallel audio track, and bar codes that, when scanned, invoke a multimedia player. The paper document provides a stand-alone representation for a video recording that lets a user both understand the content of the file and replay only selected parts of the multi...

Several models for the print-and-scan channel are available in the literature. We describe a new channel model specifically tuned to the transmission of two-dimensional bar codes and which is suitable not only for scanners, but also for time/space-variant scenarios including web cameras or those embedded in mobile phones. Our model provides an analytical expression for accurately representing t...

Monitoring of machines, machine tools and robots in local manufacturing systems, especially the monitoring of communication between machines, robots work centers and other networked devices in computer integrated manufacturing is an important part of security assurance in a global manufacturing environment. The presented monitoring methods use 2D bar code technology including QR codes and Datam...
