Name
fhtPhase - find Fourier transform phase from Hartley transform
Syntax
fhtPhase [-t <title>] <inimage> <outimage>
Description
fhtPhase calculates the Fourier transform phase
from a Hartley transform. The phase is identical
to the phase calculated from the Fourier transform,
and the hartley transform is significantly faster.
The phase values are in the interval 0..2PI.
