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 ... -
A NEW PARALLEL POLYNOMIAL DIVISION BY A SEPARABLE POLYNOMIAL VIA HERMITE INTERPOLATION WITH APPLICATIONS
Kechriniotis, A. I.; Delibasis, K. K.; Tsonos, C.; Petropoulos, N. (2012)A new parallel division of polynomials by a common separable divisor over a perfect field is presented and this is done by expressing the remainders as derivatives of a unique polynomial. In order to get this results, a ... -
On Generalizations of Gruss Inequality in Inner Product Spaces and Applications
Kechriniotis, A. I.; Delibasis, K. K. (2010)Using a Kurepa's result for Gramians, we achieve refinements of well-known generalizations of Gruss inequality in inner product spaces. These results are further applied in L(2)(a, b) to derive improvements of some published ... -
Towards the mathematic formalization of parametric generalized cylinders and initial results in modeling 3D image data
Kechriniotis, A. I.; Delibasis, K. K.; Tsonos, C.; Assimakis, N.; Asvestas, P. (2009)Generalized cylinders (GCs) have been proposed in computer vision for object modeling in two dimensional images. However approaches so far have not investigated closed form solutions, based on a formal generic definition ...
