Linear and nonlinear filtering of spectra
JOURNAL OF VACUUM SCIENCE & TECHNOLOGY B, 37(5).
The authors investigate linear and nonlinear methods of reducing noise while preserving information in spectra, optical and otherwise. The optimum linear and nonlinear approaches are Gauss–Hermite and maximum-entropy, respectively. However, intelligent processing still requires an initial assessment of the data in reciprocal space.
