Long Description

Domain Transform application for wavelet and fourier

Parameters

• Input Image (in): This will take an input image to be transformed image. For FFT inverse transform, it expects a complex image as two-band image in which first band represent real part and second band represent imaginary part.

• Output Image (out): This parameter holds the output file name to which transformed image will be written. This has a slightly different behaviour depending on transform type.
  For Wavelet, output is a single band image for both forward and inverse transform.
  For FFT forward transform, output is two band image where first band represents real part and second band represents imaginary part of a complex image.

• Mode (mode): This parameter allows one to select between fft(fourier) and wavelet

  • FFT transform (fft): FFT transform

    • Shift fft transform (mode.fft.shift): Shift transform of fft filter

  • Wavelet (wavelet): Wavelet transform

    • Select wavelet form (mode.wavelet.form):

      • HAAR (haar):

      • DAUBECHIES4 (db4):

      • DAUBECHIES6 (db6):

      • DAUBECHIES8 (db8):

      • DAUBECHIES12 (db12):

      • DAUBECHIES20 (db20):

      • SPLINE_BIORTHOGONAL_2_4 (sb24):

      • SPLINE_BIORTHOGONAL_4_4 (sb44):

      • SYMLET8 (sym8):

    • Number of decomposition levels (mode.wavelet.nlevels): Number of decomposition levels




• Direction (direction):

  • Forward (forward):

  • Inverse (inverse):



• Available RAM (Mb) (ram): Available memory for processing (in MB)

• Load otb application from xml file (inxml): Load otb application from xml file

• Save otb application to xml file (outxml): Save otb application to xml file

Limitations

This application is not streamed, check your system resources when processing large images
