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…
Improving snore detection under limited dataset through harmonic/percussive source separation and convolutional neural networks
F. D. Gonzalez-Martinez, J. J. Carabias-Orti, F. J. Canadas-Quesada +3
Snoring, an acoustic biomarker commonly observed in individuals with Obstructive Sleep Apnoea Syndrome (OSAS), holds significant potential for diagnosing and monitoring this recogn…
