An Adaptive Thresholding Image Filter
starstarstarstarstar
An Insight Toolkit (ITK) algorithm for adaptively thresholding images is presented in this paper. Currently, the usage of thresholding methods in ITK has made use of global thresholds, confidence connected thresholds and neighborhood strategies. The current [...]

Support for Streaming the JPEG2000 File Format
starstarstarstarstar
This paper describes our contribution of two new classes to the Insight Toolkit (ITK) community. This includes a base and derived ImageIO class for the JPEG2000 file formats based on the openjpeg-v2 libraries. In the current release of ITK, support for [...]

Microscopy Image Analysis: Blob Segmentation using Geodesic Active Contours
No opinion
An Insight Toolkit (ITK) processing framework for blob segmentation with applications to microscopy images is presented in this paper. Our algorithm is a reļ¬nement of the work of Mosaliganti et al. [3] for splitting cell clusters. The basic idea is to [...]

An Optimized N-Dimensional Hough Filter for Detecting Spherical Image Objects
starstarstarstarstar
An Insight Toolkit (ITK) algorithm for detection of spherical objects using Hough methods with voting is presented in this paper. Currently, the usage of Hough methods for detecting linear and circular elements exists for 2D images in ITK. The current work [...]

ITK-based Registration of Large Images from Light Microscopy: A Biomedical Application
starstarstarstarstar
Inactivation of the retinoblastoma gene in mouse embryos results in morphological changes in the placenta, which has been shown to affect fetal survivability. The construction of a 3D virtual placenta aids in accurately quantifying structural changes [...]

Impact of motion correction on the quantitative analysis of DCE-MR Images
starstarstarstarstar
Dynamic magnetic resonance imaging (DCE-MRI) carried out with contrast media such as Gd-chelate complex (Gd-DTPA) allows the non-invasive assessment of microcirculatory characteristics of malignant lesions. Quantitative estimation of lesion [...]

level set segmentation using coupled active surfaces
No opinion
An Insight Toolkit (ITK) processing framework for simultaneous segmentation of multiple objects using active contours without edges is presented in this paper. These techniques are also popularly referred to as multiphase methods. Earlier, we had an [...]

Cell Tracking using Coupled Active Surfaces for Nuclei and Membranes
No opinion
An Insight Toolkit (ITK) processing framework for segmenting and tracking nuclei in time-lapse microscopy images using coupled active contours is presented in this paper. We implement the method of Dufour et al.[2] to segment and track cells in fluorescence [...]

CTest Integration of Sikuli Automated GUI Testing
No opinion
In order to test our software GoFigure2 for the visualization and the processing of extremely large 3D+t microscopy images, we utilized the visual programming technology Sikuli to automate our GUI testing. We then integrated these Sikuli tests into CTest [...]

Level Set Segmentation: Active Contours without edge
starstarstarstarstar
An Insight Toolkit (ITK) processing framework for segmentation using active contours without edges is presented in this paper. Our algorithm is based on the work of Chan and Vese [1] that uses level- sets to accomplish region segmentation in images with [...]

A simple Qt based comparison program for ITK and VTK images.
starstarstarstarstar
This document describes a project that can compare many images simultaneously in a synchronized manner. Such an application can be used in any ITK/VTK image processing pipelines; the programmer can use it to quickly visualize and compare intermediate results [...]
