Wavelets on Trees

General Information

• This website provides source code for wavelet transforms on trees, with applications to:
  • Distributed data compression for wireless sensor networks
  • Image coding

• Publications describing these transforms can be found at:
  • Distributed Compression for Sensor Networks web page for transforms used in WSN
  • Godwin Shen's web page for transforms used in image coding (and WSN)
