DetailsDetails

  • CDFWavelet defines a set of biorthogonal wavelets.
  • The following forms can be used:
  • "5/3"used in lossless JPEG2000 compression
    "9/7"used in lossy JPEG2000 compression
  • The scaling function () and wavelet function () have compact support. The functions are symmetric.
  • CDFWavelet can be used with such functions as DiscreteWaveletTransform, WaveletPhi, etc.
