Automatic Tuberculosis and COVID-19 cough classification using deep learning

no code implementations11 May 2022 Madhurananda Pahar, Marisa Klopper, Byron Reeve, Rob Warren, Grant Theron, Andreas Diacon, Thomas Niesler

This cough data include 1. 68 hours of TB coughs, 18. 54 minutes of COVID-19 coughs and 1. 69 hours of healthy coughs from 47 TB patients, 229 COVID-19 patients and 1498 healthy patients and were used to train and evaluate a CNN, LSTM and Resnet50.

Accelerometer-based Bed Occupancy Detection for Automatic, Non-invasive Long-term Cough Monitoring

no code implementations8 Feb 2022 Madhurananda Pahar, Igor Miranda, Andreas Diacon, Thomas Niesler

When integrated into a complete cough monitoring system, the daily cough rate of a patient undergoing TB treatment was determined over a period of 14 days.

Wake-Cough: cough spotting and cougher identification for personalised long-term cough monitoring

no code implementations7 Oct 2021 Madhurananda Pahar, Marisa Klopper, Byron Reeve, Rob Warren, Grant Theron, Andreas Diacon, Thomas Niesler

We present `wake-cough', an application of wake-word spotting to coughs using a Resnet50 and the identification of coughers using i-vectors, for the purpose of a long-term, personalised cough monitoring system.

Automatic non-invasive Cough Detection based on Accelerometer and Audio Signals

no code implementations31 Aug 2021 Madhurananda Pahar, Igor Miranda, Andreas Diacon, Thomas Niesler

We present an automatic non-invasive way of detecting cough events based on both accelerometer and audio signals.

COVID-19 Detection in Cough, Breath and Speech using Deep Transfer Learning and Bottleneck Features

no code implementations2 Apr 2021 Madhurananda Pahar, Marisa Klopper, Robin Warren, Thomas Niesler

We present an experimental investigation into the effectiveness of transfer learning and bottleneck feature extraction in detecting COVID-19 from audio recordings of cough, breath and speech.

Automatic Cough Classification for Tuberculosis Screening in a Real-World Environment

no code implementations23 Mar 2021 Madhurananda Pahar, Marisa Klopper, Byron Reeve, Grant Theron, Rob Warren, Thomas Niesler

Objective: The automatic discrimination between the coughing sounds produced by patients with tuberculosis (TB) and those produced by patients with other lung ailments.

Deep Neural Network based Cough Detection using Bed-mounted Accelerometer Measurements

no code implementations9 Feb 2021 Madhurananda Pahar, Igor Miranda, Andreas Diacon, Thomas Niesler

Since the need to gather audio is avoided and therefore privacy is inherently protected, and since the accelerometer is attached to the bed and not worn, this form of monitoring may represent a more convenient and readily accepted method of long-term patient cough monitoring.

COVID-19 Cough Classification using Machine Learning and Global Smartphone Recordings

no code implementations2 Dec 2020 Madhurananda Pahar, Marisa Klopper, Robin Warren, Thomas Niesler

We present a machine learning based COVID-19 cough classifier which can discriminate COVID-19 positive coughs from both COVID-19 negative and healthy coughs recorded on a smartphone.
