In this work, we are primarily concerned with the accurate and fast segmentation of 3D medical images. The presence of a significant amount of noise in such images makes known segmentation methods...

Smoothing 2-D or 3-D Images Using Local Classification (2007)
K. Haris, G. Tziritas, S. Orphanoudakis
We propose a new method for smoothing 2-D (or 3-D) images which preserves edge elements. Pixel data contained within a moving square (or cube), centered at each point under consideration, is tested...
Hierarchical Image Segmentation Based On Contour Dynamics (2007)
K. Haris, S. Efstratiadis, N. Maglaveras
In this paper, we propose an image segmentation method based on morphological decomposition and graph-based region merging using contour dynamics. The input image is initially decomposed into a set...
Artery Skeleton Extraction Using Topographic and Connected Component Labeling (2001)
K. Haris, S. Efstratiadis, N. Maglaveras, J. Gourassas, G. Louridas
In this paper, we propose a novel method for the extraction of coronary artery skeletons (centerlines) by analyzing the topographic features of coronary angiogram images. Initially, the angiogram is...
Hybrid Image Segmentation Using Watersheds (1996)
K. Haris, S.N. Efstratiadis, N. Maglaveras, C. Pappas
A hybrid image segmentation algorithm is proposed which combines edge- and region-based techniques through the morphological algorithm of watersheds. The algorithm consists of the following steps: a)...
