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 (http://imagej.nih.gov/ij/docs/ImageFFT/). 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
