More and more images have been generated in digital form around the world. There is a
growing interest in finding images in large collections or from remote databases. In order to …

Vascular segmentation has recently been given much attention. This review paper has two
parts. Part I of this review focused on the physics of magnetic resonance angiography (MRA) …

The concept of ridges has appeared numerous times in the image processing liter ature.
Sometimes the term is used in an intuitive sense. Other times a concrete definition is …

Believing that figural zoom invariance and the cross-figural boundary linking implied by
medial loci are important aspects of object shape, we present the mathematics of and …

Presents a new algorithm for the robust and accurate tracking of the aorta in cardiovascular
magnetic resonance (MR) images. First, a rough estimate of the location and diameter of the …

This paper proposes a robust and accurate method for measuring 3-D surfaces using a
binocular system. To eliminate the effect caused by the distortion of projector lens, each …

Crease surfaces are two-dimensional manifolds along which a scalar field assumes a local
maximum (ridge) or a local minimum (valley) in a constrained space. Unlike isosurfaces …

A method is presented that aims at segmenting and measuring the surface of the spinal cord
from MR images in order to detect and quantify atrophy. A semiautomatic segmentation with …

Recent, rapid advances in mathematical engineering and applied mathematics have
opened the door to solving complex problems in angiography imaging. For the first time, this …

We introduce a versatile framework for characterizing and extracting salient structures in
three-dimensional symmetric second-order tensor fields. The key insight is that degenerate …
