Breast MRI Multi-Tumor Segmentation using 3D Region Growing
Pelicano, Ana Catarina; Godinho, Daniela M.; Gonçalves, Maria C. T.; Castela, Tiago; Orvalho, Maria Lurdes; Sencadas, Vitor; Sebastião, RaquelBreast tumor is one of the most prominent indicators for diagnosis of breast cancer. Magnetic Resonance Imaging (MRI) is a relevant imaging modality tool for breast cancer screening. Moreover, an accurate 3D segmentation of breast tumors from MRI scans plays a key role in the analysis of the disease. This paper presents a pipeline to automatically segment multiple tumors in breast MRI scans, following the metho...
Biometric recognition: a systematic review on electrocardiogram data acquisitio...
Pereira, Teresa M. C.; Conceição, Raquel C.; Sencadas, Vítor; Sebastião, RaquelIn the last decades, researchers have shown the potential of using Electrocardiogram (ECG) as a biometric trait due to its uniqueness and hidden nature. However, despite the great number of approaches found in the literature, no agreement exists on the most appropriate methodology. This paper presents a systematic review of data acquisition methods, aiming to understand the impact of some variables from the dat...
Initial study using electrocardiogram for authentication and identification
Pereira, Teresa M. C.; Conceição, Raquel C.; Sebastião, RaquelRecently, several studies have demonstrated the potential of electrocardiogram (ECG) to be used as a physiological signature for biometric systems (BS). We investigated the potential of ECG as a biometric trait for the identification and authentication of individuals. We used data from a public database, CYBHi, containing two off-the-person records from 63 subjects, separated by 3 months. For the BS, two templa...
