Blind Source Separation -> f-SOBI

Basics

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.

Example

From these sources:

The following mixtures were computed:

An the sources evaluated back using f-SOBI:
