US Patent 7,519,514. Systems and methods for removing noise from spectral data. Inventor: Randy Keith Roushall. Assignee: Agilent Technologies
In the method described, a noise burst level is defined, and if a spectral point has an intensity point greater than the burst level, points neighboring the burst point are examined. "If a function of these neighboring points indicates that the burst point is a discrete event, then the abundance level of the burst point is altered," according to the abstract.
