Foil 65 T2: Compression -- Implementation Contd.(3)

From Collaborative and Interactive Visualization Project Overview Kickoff Meeting at NPAC -- October 17,1995. by Geoffrey C. Fox * See also color IMAGE
Investigation of various video compression technologies
  • mJPEG, MPEG, H.261, MVC1, Fractal, Wavelet
Wavelet-based implementation of hierarchical motion compensation and 3D subband coding already reported in the literature
Wavelet video compressor
  • removal of temporal redundancy by compression difference between neighboring frames
  • implementing of 3D subband coding require many frames in memory and better investigation of motion estimation techniques
  • Real time, low- and high-resolution requirements - the most difficult aspect of video compression
Focus: transport over low bandwidth ISDN network (BRI 2B + D = 144 Kbps)
