Directed Curvature Histograms for Robotic Grasping
(The Eurographics Association, 2017)
Three-dimensional descriptors are a common tool nowadays, used in a wide range of tasks. Most of the descriptors that have been proposed in the literature focus on tasks such as object recognition and identification. This ...
Matching of Deformable Shapes with Topological Noise
(The Eurographics Association, 2016)
A particularly challenging setting of the shape matching problem arises when the shapes being matched have topological artifacts due to the coalescence of spatially close surface regions - a scenario that frequently occurs ...
SymPan: 3D Model Pose Normalization via Panoramic Views and Reflective Symmetry
(The Eurographics Association, 2013)
A novel pose normalization method, based on panoramic views and reflective symmetry, is presented. Initially, the surface of a 3D model is projected onto the lateral surface of a circumscribed cylinder, aligned with the ...
Towards an Observer-oriented Theory of Shape Comparison
(The Eurographics Association, 2016)
In this position paper we suggest a possible metric approach to shape comparison that is based on a mathematical formalization of the concept of observer, seen as a collection of suitable operators acting on a metric space ...
An Edit Distance for Reeb Graphs
(The Eurographics Association, 2016)
We consider the problem of assessing the similarity of 3D shapes using Reeb graphs from the standpoint of robustness under perturbations. For this purpose, 3D objects are viewed as spaces endowed with real-valued functions, ...
An Experimental Shape Matching Approach for Protein Docking
(The Eurographics Association, 2016)
Proteins play a vital role in biological processes, with their function being largely determined by their structure. It is important to know what a protein binds, where it binds, how it binds, and what is its final ...
Shape Retrieval of Low-Cost RGB-D Captures
(The Eurographics Association, 2016)
RGB-D cameras allow to capture digital representations of objects in an easy and inexpensive way. Such technology enables ordinary users to capture everyday object into digital 3D representations. In this context, we present ...
Partial Matching of Deformable Shapes
(The Eurographics Association, 2016)
Matching deformable 3D shapes under partiality transformations is a challenging problem that has received limited focus in the computer vision and graphics communities. With this benchmark, we explore and thoroughly ...
SHREC'13 Track: Retrieval of Objects Captured with Low-Cost Depth-Sensing Cameras
(The Eurographics Association, 2013)
The SHREC'13 Track: Retrieval of Objects Captured with Low-Cost Depth-Sensing Cameras is a first attempt at evaluating the effectiveness of 3D shape retrieval algorithms in low fidelity model databases, such as the ones ...
A Spatio-Temporal Descriptor for Dynamic 3D Facial Expression Retrieval and Recognition
(The Eurographics Association, 2015)
The recent availability of dynamic 3D facial scans has spawned research activity in recognition based on such data. However, the problem of facial expression retrieval based on dynamic 3D facial data has hardly been addressed ...
