An ambient denoising method based on multi-channel non-negative matrix factorization for wheezing detection
Antonio J. Muñoz-Montoro, Pablo Revuelta-Sanz, Damian Martínez-Muñoz +2
In this paper, a parallel computing method is proposed to perform the background denoising and wheezing detection from a multi-channel recording captured during the auscultation pr…
Unsupervised detection and classification of heartbeats using the dissimilarity matrix in PCG signals
J. Torre-Cruz, D. Martinez-Munoz, N. Ruiz-Reyes +3
The proposed system consists of a two-stage cascade. The first stage performs a rough heartbeat detection while the second stage refines the previous one, improving the temporal lo…
An incremental algorithm based on multichannel non-negative matrix partial co-factorization for ambient denoising in auscultation
Juan De La Torre Cruz, Francisco Jesus Canadas Quesada, Damian Martinez-Munoz +3
The aim of this study is to implement a method to remove ambient noise in biomedical sounds captured in auscultation. We propose an incremental approach based on multichannel non-n…
