We have developed the following collaborative technologies:
  • TANGO Interactive - a Web collaboratory
  • 3D visualization and collaboration system
  • Videoconferencing system
All these technologies are integrated
There are separate slide sets for each of those
There are numerous collaboratory applications developed for these systems, especially for TANGO

Foil 6 Collaborative Applications

From Command and Control Application in CIV Project Rome Laboratory CIV Final Review -- 9 April 98. *
Full HTML Index
All collaborative applications are developed on top of the basic collaboration technologies
Weather and C2 applications were driving forces of the development of collaboratory framework
Medical and ELM applications merely use the collaborative framework for visualization
Collaboratory frameworks are currently used in other fileds:
  • education and training
  • XII (eXtreme Information Infrastructure)

Developed and implemented wavelet compression for diagnostic quality color medical images
Developed and implemented wavelet compression methods for 3D imaging
Developing wavelet compression for video
  • introducing all-pass filters to improve codec performance
Implemented nearly real time H263 software encoder

Foil 9 Wavelet image compression

From Command and Control Application in CIV Project Rome Laboratory CIV Final Review -- 9 April 98. *

Technology:
  • 9,7 biorthogonal filters, dyadic decomposition, floating point transform
  • zerotree quantization, order-1 adaptive arithmetic coder
Tradeoffs:
  • advantages: embedded format (streaming), fast decoding in smaller resolutions (search, thumbnails), distortions forgivable by human visual system (space/frequency balance), high compression ratios and good quality
  • disadvantages: computationally expensive (video), lossy even at low ratios (medicine)

Foil 10 Wavelet compression

From Command and Control Application in CIV Project Rome Laboratory CIV Final Review -- 9 April 98. *

Applications:
  • natural scenes, elevation data, images with spacially concentrated details
Quality:
  • at high compression ratios significantly better than JPEG (behind JPEG limit, wavelets are still doing well)
  • better than available commercial wavelet compressors (InfinOp LightningStrike, Aware AccuPress), and public domain software
