Biologically inspired region of interest selection for low bit-rate video coding
(2006)A variety of approaches have been proposed in the literature for Region-Of-Interest (ROI) estimation. In most of them the ROI definition is highly subjective, i.e., lacks scientific evidence in supporting the claim that ...

Completely automated multiresolution edge snapper (CAMES): A new technique for an accurate carotid ultrasound IMT measurement and its validation on a multi-institutional database
(2011)Since 2005, our research team has been developing automated techniques for carotid artery (CA) wall segmentation and intima-media thickness (IMT) measurement. We developed a snake-based technique (which we named CULEX 1,2), ...

Global optimization for motion estimation with applications to ultrasound videos of carotid artery plaques
(2010)Motion estimation from digital video is an ill-posed problem that requires a regularization approach. Regularization introduces a smoothness constraint that can reduce the resolution of the velocity estimates. The problem ...

Multi-scale AM-FM motion analysis of ultrasound videos of carotid artery plaques
(2012)An estimated 82 million American adults have one or more type of cardiovascular diseases (CVD). CVD is the leading cause of death (1 of every 3 deaths) in the United States. When considered separately from other CVDs, ...

Numerical modeling of turbulent airflow and particle deposition in a bifurcating airway model
(Affiliation: UCY-CompSci Computational Sciences Laboratory, Department of Mechanical and Manufacturing Engineering, University of Cyprus, Nicosia, CyprusCorrespondence Address: Radhakrishnan, H.UCY-CompSci Computational Sciences Laboratory, Department of Mechanical and Manufacturing Engineering, University of Cyprus, Nicosia, Cyprus, 2009)Understanding transport and deposition of inhaled particles in the human airways plays a crucial role in the targeted therapy of pulmonary diseases, and the administration of inhaled medicines. Numerous researchers have ...

Primal and dual problems in electrical impedance imaging
(2005)Ill-posed inverse boundary value problems are usually approached as problems of inference under a given set of boundary observations. The parameters and data are modelled as random variables so that to encompass the ...

Αποδόμηση εικόνας με την χρήση μοντέλων AM-FM βασισμένη σε πολλαπλές οικογένειες φίλτρων Gabor και εφαρμογές σε ιατρικές εικόνες
(Πανεπιστήμιο Κύπρου, Σχολή Θετικών και Εφαρμοσμένων Επιστημών / University of Cyprus, Faculty of Pure and Applied Sciences, 2018-01)Η πολύ-κλιμακωτή αποδόμηση μη στατικών εικόνων μέσω της αναπαράστασης AM-FM έχει αποδειχθεί ότι αποτελεί μια εύρωστη μεθοδολογία ανάλυσης εικόνων. Επιπλέον τα μοντέλα AM-FM έχουν συσχετισθεί με τα μαθηματικά μοντέλα του ...
