Virtual Source Synthetic Aperture for Accurate Lateral Displacement Estimation in Ultrasound Elastography
Morteza Mirzaei, Amir Asif, Hassan Rivaz
Ultrasound elastography is an emerging noninvasive imaging technique wherein pathological alterations can be visualized by revealing the mechanical properties of the tissue. Estima…
Plane-Wave Ultrasound Beamforming Through Independent Component Analysis
Sobhan Goudarzi, Amir Asif, Hassan Rivaz
Beamforming in plane-wave imaging (PWI) is an essential step in creating images with optimal quality. Adaptive methods estimate the apodization weights from echo traces acquired by…
FS-HGR: Few-shot Learning for Hand Gesture Recognition via ElectroMyography
Elahe Rahimian, Soheil Zabihi, Amir Asif +3
This work is motivated by the recent advances in Deep Neural Networks (DNNs) and their widespread applications in human-machine interfaces. DNNs have been recently used for detecti…
Siamese Neural Networks for EEG-based Brain-computer Interfaces
