Automatic Coronary Tree Modeling (2008)
In this paper, we present an automatic method for extracting center axis representations (centerlines) of coronary arteries in contrast enhanced (CE)-CT angiography scans. The algorithm first detects...
Perceptual Organization as Object Recognition Divided by Two 1 Background (2008)
Marc Johannes, Thomas B. Sebastian, Huseyin Tek, Benjamin B. Kimia
Perceptual grouping is the organization of visual elements into groups which depict an increased level of regularity. Gestalt psychologists posited that visual elements should be grouped based on...
Automatic Volumetric Segmentation of Three-Dimensional Medical Images (2007)
Huseyin Tek, Benjamin B. Kimia
Introduction The automatic segmentation of three-dimensional medical images into anatomically relevant structures is a fundamental bottleneck in timely presentation of three-dimensional therapeutic...
Thomas B. Sebastian, Huseyin Tek, Joseph J. Crisco, Scott W. Wolfe, Benjamin B. Kimia
The in vivo investigation of joint kinematics in normal and injured wrist requires the segmentation of carpal bones from 3D (CT) images and their registration over time. The nonuniformity of bone...
Symmetry-based Indexing of Image Databases (1998)
Daniel Sharvit, Jacky Chan, Huseyin Tek, Benjamin B. Kimia
The use of shape as a cue for indexing into pictorial databases has been traditionally based on global invariant statistics and deformable templates, on the one hand, and local edge correlation on...

Shocks From Images: Propagation of Orientation Elements (1997)
Huseyin Tek, Perry A. Stoll, Benjamin B. Kimia
The extraction of figure symmetry from image contours faces a number of fundamental difficulties: object symmetries are distorted due to (i) gaps in the bounding contour of a shape due to...
Image Segmentation by Reaction-Diffusion Bubbles (1995)
Huseyin Tek, Benjamin B. Kimia
Figure-Ground segmentation is a fundamental problem in computer vision. The main difficulty is the integration of low-level, pixel-based local image features to obtain global object-based...
Shock-Based Reaction-Diffusion Bubbles for Image Segmentation (1994)
Huseyin Tek, Benjamin B. Kimia
. Figure-Ground segmentation is a fundamental problem in computer vision. The main difficulty is the integration of low-level, pixelbased local image features to obtain global object-based...
