NAME
phase, fftPhase - phase of complex image
SYNTAX
phase [<option>...] <inimage> <outimage>
fftPhase [<option>...] <inimage> <outimage>
DESCRIPTION
phasecomputes the phase of a complex image.
fftPhaseis retained for compatibility with previous XITEversions. It is a script which invokes phase.
OPTIONS
- -b
- The result will be written as a byte image, with the interval0 - 2*pi scaled to the interval 0 - 255. Default: The resultwill be scaled to the interval 0 - 2pi on a real image.
- -shift
- The resulting bands are shifted horizontally xsize/2,vertically ysize/2. This is convenient to be able to centerthe (0,0) frequency of a Fourier transform image.
RETURN VALUE
0 - OK
1 - Bands have different horizontal size
2 - Bands have different vertical size
3 - Input band has wrong pixeltype
4 - Output band has wrong pixeltype
5 - Error in shift_band.
