A New Non-Negative Matrix Co-Factorisation Approach for Noisy Neonatal Chest Sound Separation [PDF]
2021 43rd Annual International Conference of the IEEE Engineering
in Medicine Biology Society (EMBC), 2021 Obtaining high-quality heart and lung sounds enables clinicians to accurately assess a newborn's cardio-respiratory health and provide timely care. However, noisy chest sound recordings are common, hindering timely and accurate assessment. A new Non-negative Matrix Co-Factorisation-based approach is proposed to separate noisy chest sound recordings ...

A Method for Detecting Murmurous Heart Sounds based on Self-similar Properties [PDF]
arXiv, 2023 A heart murmur is an atypical sound produced by the flow of blood through the heart. It can be a sign of a serious heart condition, so detecting heart murmurs is critical for identifying and managing cardiovascular diseases. However, current methods for identifying murmurous heart sounds do not fully utilize the valuable insights that can be gained by ...
