Color-Enhanced Spectral Transient Analysis Method

      A method of enhancing the recognition of spectral
transients is disclosed.  The method, which is based on time-stamping
spectral data by color, is referred to as color-enhanced spectral
transient analysis method (CESTAM).

      CESTAM provides the ability to aid in the recognition of
spectral (or temporal) transients by associating a distinctive color
transition to a particular spectral transient.  Thus, the time
dimension is replaced by color. Note that this method is also of use
in traditional 2-D time-frequency plots (i.e., waterfall displays).
In this case, the use of color merely accentuates the transients.

      The method is described by the pseudocode below.  The key
variables in the algorithm are: CurrentData          The most recent
data available. Delta                The value of delta determines
how far back in time one wishes to see data.  Delta=0 corresponds to
no past data, i.e., only current data is view                     ed.
Color                Vector which contains the range of colors to
use.
