A system and method of signal denoising using Independent Component Analysis (ICA) and fractal dimension analysis of the signal components in the ICA domain is described. The signal components with fractal dimensions higher than a pre-determined threshold are automatically attenuated or canceled in order to alleviate the noise in the signal. The denoised signal is reconstructed using inverse ICA transform of the signal components.
L'invention porte sur un système et sur un procédé de débruitage de signal à l'aide d'une analyse de composant indépendant (ICA) et d'une analyse de dimension fractale des composants de signal dans le domaine ICA. Les composants de signal avec des dimensions fractales supérieures à un seuil prédéterminé sont automatiquement atténués ou annulés afin de soulager le bruit dans le signal. Le signal débruité est reconstruit à l'aide d'une transformée ICA inverse des composants de signal.
