A classification system based on a new wrapper feature selection algorithm for the diagnosis of primary and secondary polycythemia
Korfiatis, V. C.; Asvestas, P. A.; Delibasis, K. K.; Matsopoulos, G. K. (2013)Primary and Secondary Polycythemia are diseases of the bone marrow that affect the blood's composition and prohibit patients from becoming blood donors. Since these diseases may become fatal, their early diagnosis is ... -
A Fourier-based implicit evolution scheme for active surfaces, for object segmentation in volumetric images
Delibasis, K. K.; Tassani, S.; Asvestas, P.; Kechriniotis, A. I.; Matsopoulos, G. K. (2013)Active contours (AC) and active surfaces (AS) have been used extensively for segmentation and measurement in two- and three-dimensional images. The small time steps used in discretizing the evolution equation of AC/AS with ... -
Hermite Kernels for slice interpolation in medical images
Delibasis, K. K.; Kechriniotis, A. I.; Assimakis, N. D.; Tassani, S.; Matsopoulos, G. K. (2012)Univariate Hermite interpolation of the total degree (HTD) is an algebraically demanding interpolation method that utilizes information of the values of the signal to be interpolated at distinct support positions, as well ... -
An implicit evolution scheme for active contours and surfaces based on IIR filtering
Delibasis, K. K.; Asvestas, P. A.; Kechriniotis, A. I.; Matsopoulos, G. K. (2014)In this work, we present an approach for implementing an implicit scheme for the numerical solution of the partial differential equation of the evolution of an active contour/surface. The proposed scheme is applicable to ...
