Detecção de ataques a sistemas de reconhecimento facial utilizando abordagens eficientes de aprendizado de máquina em profundidade
(Universidade Federal de São Carlos, 2019-05-21)
Biometrics emerged, in the last decades, as a robust and convenient solution for security systems. However, despite the higher difficulty to circumvent the biometric applications, nowadays, criminals are developing attacks, ...
Redução de ruído speckle em imagens de ultrassom com filtragem não-local e distâncias estocásticas
(Universidade Federal de São Carlos, 2017-12-08)
Ultrasound imaging is one of the most used modalities in medicine since it is low cost and has no ionizing radiation. However, ultrasound images are corrupted by a signal-dependent noise, known as speckle, causing a granular ...
