Title:
DENOISING METHOD BY SIGNAL RECONSTRUCTION FROM PARTIAL SPECTRUM DATA
Document Type and Number:
WIPO Patent Application WO/2008/148250
Kind Code:
A1
Abstract:
A denoising method by signal reconstruction from partial spectrum data includes
the steps of: extracting various partial spectrum data from an intact signal
spectrum space according to different frequency ranges, reconstructing a plurality
of observing signals from the partial spectrum data above using complex singular
spectrum analysis, and according to the plurality of reconstructed observing
signals above, performing signal denoising by multiple observing signals averaging.
With the denoising method by signal reconstruction from partial spectrum data,
it has a combined advantage of denoising by multiple observing signals averaging
and single observing signal denoising, scanning time is saved, image noise is
effectively removed, and signal-to-noise ratio is improved.
