摘要

本文提出了一种用于听觉咳嗽信号的相关分形维数表征方法。我们从患有和未患有Covid-19疾病的人那里获得了咳嗽样本。我们的假设是来自Covid-19疾病的咳嗽表现出分形行为。为了证明这一点,我们在两个样本上应用分形尺寸测量。初步结果证实了Covid-19咳嗽信号的分形。这一结果可以提高识别Covid-19等呼吸系统疾病的预筛查性能。

A Fractal Characterization of Cough Signals for Covid-19 Pre-Screening Applications
This paper presents a correlation fractal dimension characterization as applied to auditory cough signals. We have obtained cough samples from person with and without Covid-19 disease. Our hypothesis is coughs coming from Covid-19 disease exhibit fractal behavior. To show this, we apply fractal-size measurements on both samples. Preliminary results confirm fractality on Covid-19 cough signals. This result can improve performance of pre-screening for identification the presence respiratory diseases, such as Covid-19.
