Vessel segmentation algorithms are the critical components of circulatory blood vessel
analysis systems. We present a survey of vessel extraction techniques and algorithms. We …

Curve-skeletons are thinned 1D representations of 3D objects useful for many visualization
tasks including virtual navigation, reduced-model formulation, visualization improvement …

The last half century has seen the development of many biological or physical t-ories that
have explicitly or implicitly involved medial descriptions of objects and other spatial entities …

Many approaches have been proposed to solve the problem of finding the optic flow field of
an image sequence. Three major classes of optic flow computation techniques can …

A model of object shape by nets of medial and boundary primitives is justified as richly
capturing multiple aspects of shape and yet requiring representation space and image …

Methods, Systems, and computer program products are provided for automatic image
recognition of Standard shapes which include a core-based deformable loci Skeletal grid …

Introduces a technique for the automated description of tubular objects in 3D medical
images. The goal of automated 3D object description is to extract a representation which …

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 …

Evidence suggests that some structural brain abnormalities in schizophrenia are
neurodevelopmental in origin. There is also growing evidence to suggest that shape …

Blum's medial axes have great strengths, in principle, in intuitively describing object shape
in terms of a quasi-hierarchy of figures. But it is well known that, derived from a boundary …
