ica: Spectral unmixing: Independent Component Analysis (ICA)

In konradmayer/hyperSpec.utils: Utility functions to work with objects of the hyperSpec class

Description

This is a wrapper around fastICA from the package fastICA to be used with objects of class hyperSpec.

Usage

ica(x, ncomp, prefix = "basis", ...)

Arguments

x	a hyperSpec object.
ncomp	integer; number of pure components.
prefix	character; a prefix to name the pure spectra.
...	further arguments to be passed down to fastICA.

Value

a list with the following components:

coefficients

coefficient matrix

basis

a hyperSpec object containing the basis (component) spectra

fit

the ica fit as returned by fastICA
