CONSTRAINED QUADRILATERAL MESHES OF BOUNDED SIZE (2008)
Suneeta Ramaswami, Marcelo Siqueira, Tessa Sundaram, Jean Gallier, James Gee
We introduce a new algorithm to convert triangular meshes of polygonal regions, with or without holes, into strictly convex quadrilateral meshes of small bounded size. Our algorithm includes all...
5 6 Topological Repairing of 3D Digital Images (2008)
Marcelo Siqueira, Longin Jan Latecki, Nicholas Tustison, Jean Gallier, James Gee
Abstract We present here a new randomized algorithm for repairing the topology of objects represented by 3D binary digital images. By “repairing the topology”, we mean a sys-and optimized for...
Meeting Andy Warhol Somewhere Over the Rainbow: RGB Colormapping and ITK (2008)
Tustison, Nicholas, Zhang, Hui, Yushkevich, Paul, Gee, James
Although greyscale intensity values are primarily used in image data visualization oftentimes, due to the requirements of aesthetics (whether they be self-imposed or collaborator-suggested), mapping...
Run-Length Matrices For Texture Analysis (2008)
Tustison, Nicholas, Gee, James
Texture analysis provides quantitative information describing properties in images such as coarseness and smoothness. Two common quantification schemes are based on co-occurence matrices and...
Live-Wire-ing the Insight Toolkit with Intelligent Scissors (2008)
Tustison, Nicholas, Yushkevich, Paul, Gee, James
Semi-automatic image segmentation algorithms depend on interaction with the user to accurately define a region of interest within an image. Once such method is a dynamic programming approach called...
J.C.: The shape operator for differential analysis of images (2008)
Abstract. This work provides a new technique for surface oriented volumetric image analysis. The method makes no assumptions about topology, instead constructing a local neighborhood from image...
Despina Kontos, Vasileios Megalooikonomou, James Gee
We illustrate the application of intelligent medical image analysis techniques in order to reduce the computational cost of statistical voxel-wise analysis for detecting discriminative regions of...

Image Segmentation by Flexible Models Based on Robust Regularized Networks (2002)
The object of this paper is to present aform ulation for thesegmF tation and restorationproblem using flexiblem dels with a robust regularized network (RRN). A two-steps iterativealgorithm is...
Similarity measures for matching diffusion tensor images (1999)
Daniel Alex, James Gee, Ruzena Bajcsy
In this paper, we discuss matching of diffusion tensor (DT) MRIs of the human brain. Issues concerned with matching and transforming these complex images are discussed. A number of similarity...
Elastic Matching of Diffusion Tensor MRIs (1999)
Daniel Alexander James, Daniel Alex, James Gee, Ruzena Bajcsy
In this paper we discuss work on the use of diffusion tensor MRIs for inter-subject brain matching. A multiresolution elastic matching algorithm, [2-4], for spatial normalisation of 3D image data,...

Cube Analyzer - A Medical Image Analysis Program (1988)
Hoford, John, Choset, Howie, Kovacic, Stane, Gee, James, Bajcsy, Ruzena
The Cube Analyzer is a group of programs designed to analyze three-dimensional tomographic data such as CT, PET and MRI scans. It is designed to work on a Unix workstation running X-windows, and was...
Validation of plaster endocast morphology through 3D CT image analysis
Schoenemann, P. Thomas, Gee, James, Avants, Brian, Holloway, Ralph L., Monge, Janet, Lewis, Jason
A crucial component of research on brain evolution has been the comparison of fossil endocranial surfaces with modern human and primate endocrania. The latter have generally been obtained by creating...
Shape Characterization of the Corpus Callosum in Schizophrenia Using Template Deformation
Dubb, Abraham, Avants, Brian, Gur, Ruben, Gee, James
We use template deformation morphometry to demonstrate regional shape differences in the corpus callosa of 100 patients with schizophrenia. We first use a k-means clustering segmentation algorithm...
