Region Growing Using a Criterion on the Region Boundary
starstarstarstarstar
This document presents a set of classes which implement a region growing algorithm whose criterion for growth is different than existing ITK region growing algorithms. The region is grown into the query pixel based only on the difference between the query [...]

Image Segmentation: Ventricle Isolation Using Region Growing
No opinion
This document describes the process used in implementing image segmentation through a region growing algorithm with the use of the Insight Toolkit (ITK) imaging program. The code used to implement the region growing algorithm is documented in the ITK Software [...]

Segmentation Using a Region Growing Algorithm
No opinion
This document describes an example implementation of segmenting the ventricles of the brain using the Insight Toolkit. Ventricle segmentation is done using the simple confidence connected region growing algorithm. Included with this paper is the source [...]

A Conditional Mesh Front Iterator for VTK
starstarstarstarstar
Region growing is a technique that can be used to propagate information over a mesh. In a previous submission, "A Mesh Front Iterator for VTK", we introduced an iterator that can be used with vtkPointSet subclasses to traverse a mesh. It is sometimes useful [...]

A semi-automated method for liver tumor segmentation based on 2D region growing with
starstarstarstarstar
Liver tumour segmentation from computed tomography (CT) scans is a challenging task. A semi-automatic method based on 2D region growing with knowledge-based constraints is proposed to segment lesions from constituent 2D slices obtained from 3D CT images. [...]

Shaped Neighborhood based Flood Filled Conditional Iterators
starstarstarstarstar
ITK's flood filling iterator represents a way to visit pixels/voxels within an image having a specific connectivity. The iterator is initialized at known seed points and starting from these, neighbors that are within the desired connectivity are marked as to [...]

Semi-automatic Segmentation of Liver Tumors from CT Scans Using Bayesian Rule-based 3D Region Growing
starstarstarstarstar
Automatic segmentation of liver tumorous regions often fails due to high noise and large variance of tumors. In this work, a semi-automatic algorithm is proposed to segment liver tumors from computed tomography (CT) images. To cope with the variance of [...]

A Mesh Front Iterator for VTK
starstarstarstarstar
Region growing is a technique that can be used to propagate information over a mesh. We provide an iterator that can be used with vtkPointSet subclasses to traverse a mesh in a reasonable fashion. A "front" is emanated from a selected starting vertex, and the [...]

Segmentation of Skull-infiltrated Tumors Using ITK: Methods and Validation
starstarstarstarstar
Methods for segmentation of skull infiltrated tumors in Computed Tomography (CT) images using Insight Segmentation and Registration Toolkit ITK (www.itk.org) are presented. Pipelines of filters and algorithms from ITK are validated on the basis of [...]
