A new approach to denoising EEG signals - merger of translation invariant wavelet and ICA

Walters-Williams, Janett and Li, Yan (2011) A new approach to denoising EEG signals - merger of translation invariant wavelet and ICA. International Journal of Biometrics and Bioinformatics, 5 (2). pp. 130-148. ISSN 1985-2347


In this paper we present a new algorithm using a merger of Independent Component Analysis and Translation Invariant Wavelet Transform. The efficacy of this algorithm is evaluated by applying contaminated EEG signals. Its performance was compared to three fixed-point ICA algorithms (FastICA, EFICA and Pearson-ICA) using Mean Square Error (MSE), Peak Signal to Noise Ratio (PSNR), Signal to Distortion Ratio (SDR), and Amari Performance Index. Experiments reveal that our new technique is the most accurate separation method.
