Scrambling for Anonymous Visual Communications

In this paper, we present a system for anonymous visual communications. Target application is an anonymous video chat. The system is identifying faces in the video sequence by means of face detection or skin detection. The corresponding regions are subsequently scrambled. We investigate several approaches for scrambling, either in the image-domain or in the transform-domain. Experiment results ...

Future Trends in Special Library Services

Special libraries all over the world today fulfil a whole variety of different services at a wide range of locations. This diversified spectrum of activities is by no means a recent development. At the time that the Special Library Association (SLA) was founded at the 1909 conference of the American Library Association (ALA), special libraries already had little to do with traditional library t...

New Antenna Array Architectures for Satellite Communications

Ground stations which integrate the control segment of a satellite mission have as a common feature, the use of large reflector antennas for space communication. Apart from many advantages, large dishes pose a number of impairments regarding their mechanical complexity, low flexibility, and high operation and maintenance costs. hus, reflector antennas are expensive and require the installation ...

Market Trends in Global Satellite Communications - Implications for Canada
