Title:
METHODS OF LOCATING AND REMOVING SPIKE NOISE FROM SPECTRAL DATA AND METHOD OF DETECTING BAD PIXEL ELEMENTS IN A CHARGE COUPLED DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/109632
Kind Code:
A3
Abstract:
Cosmic spike filters are provided, which remove noise spikes in spectral data. Spikes are eliminated by locating, smoothing and filtering the spikes using replicates to improve the accuracy of the spike detection process compared to when only one replicate is used. Cosmic spike filters are also provided that combine a data collection approach and a statistical approach to remove cosmic spike noise from the collected signal without distorting the true signal. Still further, a statistical approach is provided to identify and remove negative peaks from a spectrum, where the negative peaks are caused by bad pixels in a charge coupled device.
