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 ... -
A modified Seeded Region Growing algorithm for vessel segmentation in breast MRI images for investigating the nature of potential lesions
Glotsos, D.; Vassiou, K.; Kostopoulos, S.; Lavdas, E.; Kalatzis, I.; Asvestas, P.; Arvanitis, D. L.; Fezoulidis, I. V.; Cavouras, D. (2014)The role of Magnetic Resonance Imaging (MRI) as an alternative protocol for screening of breast cancer has been intensively investigated during the past decade. Preliminary research results have indicated that gadolinium-agent ... -
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 ...
