Recent developments in techniques for modeling, digitizing and visualizing 3D shapes has
led to an explosion in the number of available 3D models on the Internet and in domain …

Three-dimensional shape searching is a problem of current interest in several different
fields. Most techniques have been developed for a particular domain and reduce a shape …

Skeletonization provides an effective and compact representation of objects, which is useful
for object description, retrieval, manipulation, matching, registration, tracking, recognition …

This well-accepted introduction to computational geometry is a textbook for high-level
undergraduate and low-level graduate courses. The focus is on algorithms and hence the …

We review methods designed to compute correspondences between geometric shapes
represented by triangle meshes, contours or point sets. This survey is motivated in part by …

The computer vision and pattern recognition communities have recently witnessed a surge
of feature-based methods in object recognition and image retrieval applications. These …

This paper describes a new approach for training generative adversarial networks (GAN) to
understand the detailed 3D shape of objects. While GANs have been used in this domain …

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

We present an algorithm for curve skeleton extraction via Laplacian-based contraction. Our
algorithm can be applied to surfaces with boundaries, polygon soups, and point clouds. We …

Given a shape, a skeleton is a thin centered structure which jointly describes the topology
and the geometry of the shape. Skeletons provide an alternative to classical boundary or …
