public class FFT
- extends java.lang.Object
- implements PlugIn, Measurements
This class implements the FFT, Inverse FFT and Redisplay Power Spectrum commands
in the Process/FFT submenu. It is based on Arlo Reeves'
Pascal implementation of the Fast Hartley Transform from NIH Image
The Fast Hartley Transform was restricted by U.S. Patent No. 4,646,256, but was placed
in the public domain by Stanford University in 1995 and is now freely available.
Version 2008-08-25 inverse transform: mask is always symmetrized
