Matching shapes with a reference point [PDF]
Proceedings of the tenth annual symposium on Computational geometry - SCG '94, 1994 For two given point sets, we present a very simple (almost trivial) algorithm to translate one set so that the Hausdorff distance between the two sets is not larger than a constant factor times the minimum Hausdorff distance which can be achieved in this way. The algorithm just matches the so-called Steiner points of the two sets.

Shock Graphs and Shape Matching [PDF]
International Journal of Computer Vision, 1999 We have been developing a theory for the generic representation of 2-D shape, where structural descriptions are derived from the shocks (singularities) of a curve evolution process, acting on bounding contours. We now apply the theory to the problem of shape matching.

Efficient shape matching using shape contexts [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2005 We demonstrate that shape contexts can be used to quickly prune a search for similar shapes. We present two algorithms for rapid shape retrieval: representative shape contexts, performing comparisons based on a small number of shape contexts, and shapemes, using vector quantization in the space of shape contexts to obtain prototypical shape pieces.

A SHAPE-CONTEXT MODEL FOR MATCHING PLACENTAL CHORIONIC SURFACE VASCULAR NETWORKS
Image Analysis and Stereology, 2018 Placental chorionic surface vascular networks (PCSVNs) are essential high-capacitance, low-resistance distribution and drainage networks, and are hence important to placental function and to fetal and newborn health.

3D Object Recognition in Cluttered Scenes With Robust Shape Description and Correspondence Selection
IEEE Access, 2017 Recognizing 3-D objects in cluttered scenes is a challenging task. Common approaches find potential feature correspondences between a scene and candidate models by matching sampled local shape descriptors and select a few correspondences with the highest

Matching solid shapes in arbitrary dimension via random sampling [PDF]
Discrete Mathematics & Theoretical Computer Science, 2012 We give simple probabilistic algorithms that approximately maximize the volume of overlap of two solid, i.e. full-dimensional, shapes under translations and rigid motions. The shapes are subsets of $ℝ^d$ where $d≥ 2$.

A Two-Stage Matching Method for Multi-Component Shapes
Advances in Electrical and Computer Engineering, 2015 In this paper a shape matching algorithm for multiple component objects has been proposed which aims at matching shapes by a two-stage method. The first stage extracts the similarity features of each component using a generic shape representation model.

A Multilevel Road Alignment Model for Spatial-Query-by-Sketch
Applied Sciences, 2020 A sketch map represents an individual’s perception of a specific location. However, the information in sketch maps is often distorted and incomplete. Nevertheless, the main roads of a given location often exhibit considerable similarities between the ...
