Classification of Electrical Impedance Tomography Data Using Machine Learning
Diogo Pessoa, Bruno Machado Rocha, Grigorios-Aris Cheimariotis +7
Patients suffering from pulmonary diseases typically exhibit pathological lung ventilation in terms of homogeneity. Electrical Impedance Tomography (EIT) is a non-invasive imaging…
Detection of squawks in respiratory sounds of mechanically ventilated COVID-19 patients
Bruno M. Rocha, Diogo Pessoa, Grigorios-Aris Cheimariotis +7
Mechanically ventilated patients typically exhibit abnormal respiratory sounds. Squawks are short inspiratory adventitious sounds that may occur in patients with pneumonia, such as…
Influence of Event Duration on Automatic Wheeze Classification
Bruno M. Rocha, Diogo Pessoa, Alda Marques +2
Patients with respiratory conditions typically exhibit adventitious respiratory sounds, such as wheezes. Wheeze events have variable duration. In this work we studied the influence…
Accurate Segmentation of Dermoscopic Images based on Local Binary Pattern Clustering
Pedro M. M. Pereira, Rui Fonseca-Pinto, Rui Pedro Paiva +3
Segmentation is a key stage in dermoscopic image processing, where the accuracy of the border line that defines skin lesions is of utmost importance for subsequent algorithms (e.g.…
