Influence of Event Duration on Automatic Wheeze Classification

no code implementations4 Nov 2020 Bruno M. Rocha, Diogo Pessoa, Alda Marques, Paulo Carvalho, Rui Pedro Paiva

Then, by changing one parameter in the design of the non-wheeze class, i. e., event duration, the best classifier only reached sensitivity and specificity values of 55% and 76%, respectively.

Accurate Segmentation of Dermoscopic Images based on Local Binary Pattern Clustering

no code implementations17 Feb 2019 Pedro M. M. Pereira, Rui Fonseca-Pinto, Rui Pedro Paiva, Luis M. N. Tavora, Pedro A. A. Assuncao, Sergio M. M. de Faria

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., classification) and computer-aided early diagnosis of serious medical conditions.
