This article proposes a state-space model with Cauchy observation noise (SSMC) to detect seizure onset in a long-term EEG monitoring system. Facing the challenge of high false detection rates (FDRs) in many existing methods caused by impulsive EOG/EMG artifacts, the SSMC uses a nonlinear state-space model to encode the gradual changes of epileptic seizure signals and reject abrupt changes brought...
The respiratory rate is a vital sign that can provide important information about the health of a patient, especially that of the respiratory system. The aim of this study is to develop a simple method that can be applied in wearable systems to monitor the respiratory rate automatically and continuously over extended periods of time. In this paper, a novel respiratory rate estimation method is presented...
Wheezy breath is a general sign for airway obstructive diseases like asthma and chronic obstructive pulmonary disease. This paper presents a novel wheeze detection method that can be used to detect and identify wheezes automatically. The proposed method exploits ``entropy" to describe the pattern of the frequency spectrum of the wheezing signal and the wheeze identification can be conducted using...
