The hypothesis in f-SOBI are
The algorithm strongly relies on the SOBI algorithm. Its conception and implementation were the result of a collaboration with Danielle Nuzillard.
The sources of f-SOBI, written in Matlab language, are archived in f-sobi.tar.gz, as well an example.
From these sources:
The following mixtures were computed:
An the sources evaluated back using f-SOBI:
