Changes to itk::PathToImageFilter.
No opinion
I have made some changes to make itk::PathToImageFilter to make it a usable base class. There were some problems with the CVS version, including: (1) this ase classhad actual filter functionality, (2) the mechanism for specifying the size, spacing, [...]

Fast Marching Minimal Path Extraction in ITK
This paper describes the ITK implementation of a minimal path extraction framework based on Fast Marching arrival functions. The method requires the user to provide three inputs: 1. a meaningful speed function to generate an arrival function, 2. path [...]

N-Dimensional Path Optimization:  The Implementation of a Novel Algorithm in ITK
Using the path framework we previously added to ITK, we implemented a novel algorithm for n-dimensional path optimization, which we call the ND Swath (NDS). NDS uses dynamic programming to globally optimize the placement of a path within an image, subject to [...]

ContourExtractor2DImageFilter: A subpixel-precision image isocontour extraction filter.
No opinion
This document describes itk::ContourExtractor2DImageFilter, an implementation of the arching squares2D contour-finding method using the Insight Toolkit ITK This filter takes as input a 2D image (not necessarily binarized) and a contour value, and [...]

Implementation of weighted Dijkstra’s shortest-path algorithm for n-D images
No opinion
This paper describes the ITK implementation of a shortest path extraction algorithm based on graph representation of the image and the Dijkstra shortest path algorithm. The method requires the user to provide two inputs: 1. path information in the form of [...]

Nearly automatic vessels segmentation using graph-based energy minimization
No opinion
We present a nearly automatic tool for the accurate segmentation of vascular structures in volumetric CTA images. Its inputs are a start and an end seed points inside the vessel. The two-step graph-based energy minimization method starts by computing the [...]

Minimally Interactive Knowledge-based Coronary Tracking in CTA using a Minimal Cost Path
No opinion
An algorithm for minimally interactive coronary artery tracking is presented. Tracking ability and accuracy results are demonstrated on 16 images CTA images. First, a region of interest is automatically selected and a denoising filter applied. Then, for each [...]

Two Point Minimum Cost Path Approach for CTA Coronary Centerline Extraction
No opinion
In this work a minimum cost path approach is adopted to extract coronary artery centerlines from CTA data. The algorithm depends on the manual definition of the start and end point of the vessel. The cost image used in the minimal cost path approach is based [...]

Creation and Demonstration of a Framework for Handling Paths in ITK
No opinion
A hierarchy of path data types and basic path filters were added to ITK, providing a general framework for curves that map a scalar value to a point in n-dimensional space. The framework supports curves that are either continuous (parametric curves) or [...]

A Minimal Cost Path and Level Set Evolution Approach for Carotid Bifurcation Segmentation
No opinion
We propose a new approach for semi-automatic segmentation of the carotid bifurcation as part of the Carotid Lumen Segmentation and Stenosis Grading Challenge MICCAI'2009 workshop. Three initial points are provided as input, belonging to the Common, the [...]

Carotid Lumen Segmentation Based on Tubular Anisotropy and Contours Without Edges
No opinion
We present a semi-automatic algorithm for Carotid lumen segmentation on CTA images. Our method is based on a variant of the minimal path method that models the vessel as a centerline and boundary. This is done by adding one dimension for the local radius [...]

Tubular Geodesics using Oriented Flux: An ITK Implementation
This document describes an ITK implementation of an interactive method for tracing curvilinear structures. The basic tools provided in this framework are an oriented flux-based tubularity measure and a geodesic path tracer that uses the fast marching [...]
