Fully automatized parallel segmentation of the optic disc in retinal fundus images
(Elsevier, 2016-11)
This paper presents a fully automatic parallel software for the localization of the optic disc (OD) in retinal fundus color images. A new method has been implemented with the Graphics Processing Units (GPU) technology. ...

EEG Signal Processing in MI-BCI Applications With Improved Covariance Matrix Estimators
(IEEE, 2019)
In brain-computer interfaces (BCIs), the typical models of the EEG observations usually lead to a poor estimation of the trial covariance matrices, given the high non-stationarity of the EEG sources. We propose the application ...

Effect of the side of presentation in the visual field on phase‑locked and nonphase‑locked alpha and gamma responses
(Springer Nature, 2022)
Recent studies have suggested that nonphase-locked activity can reveal cognitive mechanisms that cannot be observed in phase-locked activity. In fact, we describe a concomitant decrease in nonphase-locked alpha activity ...

The Generalized Complex Kernel Least-Mean-Square Algorithm
(Institute of Electrical and Electronics Engineers (IEEE), 2019-08)
We propose a novel adaptive kernel-based regression method for complex-valued signals: the generalized complex-valued kernel least-mean-square (gCKLMS). We borrow from the new results on widely linear reproducing kernel ...
