spikefilter2d
: These functions calculate the suspiciousness of data points by a
c (-1, 2, -1)
filter. spikefilter
applies this filter along
the spectrtal (wavelength) direction, spikefilter2d
in addition also
to neighbour spectra.
The recognition of spikes may be greatly improved by preprocesing the spectra specially for this task, see the demo.
spikefilter2d
: matrix of the same size as spcmatrix
