Title : ECG denoising based on WATV and convex fused lasso denoising with non-convex regularization
Abstract:
In this paper, we propose a novel approach of Electrocardiogram Denoising based on Wavelet/Total Variation (WATV) and Convex fused lasso Denoising with non-convex regularization. This approach consists at first step of applying the Discrete Wavelet Transform to the noisy ECG signal for obtaining a noisy approximation coefficient, and a noisy details coefficient The latter is denoised by soft thresholding and we obtain a first denoised details coefficient. The second step of this approach consists of applying the to in order to obtain a second noisy approximation coefficient and a second noisy details coefficient The latter is denoised by Convex fused lasso denoising with non-convex regularization and we obtain a second denoised details coefficient. The noisy approximation coefficient is denoised by WATV based denoising technique and we obtain a denoised approximation coefficient. The inverse of is then applied to and in order to obtain a denoised approximation coefficient. The inverse of is again applied to and for obtaining finally a denoised signal. The performance of this proposed approach is proved by the computation of the Signal to Noise Ratio (SNR), the Peak SNR (PSNR), the Mean Square Error the Mean Absolute Error and the Cross-Correlation
