Parallelized Algorithms for Rigid Surface Alignment on GPU
(The Eurographics Association, 2012)Alignment and registration of rigid surfaces is a fundamental computational geometric problem with applications ranging from medical imaging, automated target recognition, and robot navigation just to mention a few. The ... -
Parameterization Robustness of 3D Auto-Encoders
(The Eurographics Association, 2022)The generation of 3-dimensional geometric objects in the most efficient way is a thriving research topic with, for example, the development of geometric deep learning, extending classical machine learning concepts to non ... -
Part Analogies in Sets of Objects
(The Eurographics Association, 2008)Shape retrieval can benefit from analogies among similar shapes and parts of different objects. By partitioning an object to meaningful parts and finding analogous parts in other objects, sub-parts and partial match queries ... -
Partial 3D Object Retrieval combining Local Shape Descriptors with Global Fisher Vectors
(The Eurographics Association, 2015)This work introduces a partial 3D object retrieval method, applicable on both meshes and point clouds, which is based on a hybrid shape matching scheme combining local shape descriptors with global Fisher vectors. The ... -
Partial Matching for Real Textured 3D Objects using Color Cubic Higher-order Local Auto-Correlation Features
(The Eurographics Association, 2009)In recent years the need for the retrieval of real 3D objects is growing more and more. However, if the 3D models are obtained without the use of special equipment such as engineered environments or multi-camera systems, ... -
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 ... -
Partial Shape Queries for 3D Object Retrieval
(The Eurographics Association, 2016)Despite numerous recent efforts, 3D object retrieval based on partial shape queries remains a challenging problem, far from being solved. The problem can be defined as: given a partial view of a shape as query, retrieve ... -
Performing Image-like Convolution on Triangular Meshes
(The Eurographics Association, 2018)Image convolution with a filtering mask is at the base of several image analysis operations. This is motivated by Mathematical foundations and by the straightforward way the discrete convolution can be computed on a grid-like ... -
Person Independent 3D Facial Expression Recognition by a Selected Ensemble of SIFT Descriptors
(The Eurographics Association, 2010)Facial expression recognition has been addressed mainly working on 2D images or videos. In this paper, the problem of person-independent facial expression recognition is addressed on 3D shapes. To this end, an original ... -
Person Re-Identification from Depth Cameras using Skeleton and 3D Face Data
(The Eurographics Association, 2018)In the typical approach, person re-identification is performed using appearance in 2D still images or videos, thus invalidating any application in which a person may change dress across subsequent acquisitions. For example, ... -
Point-Cloud Shape Retrieval of Non-Rigid Toys
(The Eurographics Association, 2017)In this paper, we present the results of the SHREC'17 Track: Point-Cloud Shape Retrieval of Non-Rigid Toys. The aim of this track is to create a fair benchmark to evaluate the performance of methods on the non-rigid ... -
POP: Full Parametric model Estimation for Occluded People
(The Eurographics Association, 2019)In the last decades, we have witnessed advances in both hardware and associated algorithms resulting in unprecedented access to volumes of 2D and, more recently, 3D data capturing human movement. We are no longer satisfied ... -
Protein Shape Retrieval
(The Eurographics Association, 2018)Proteins are macromolecules central to biological processes that display a dynamic and complex surface. They display multiple conformations differing by local (residue side-chain) or global (loop or domain) structural ... -
Protein Shape Retrieval
(The Eurographics Association, 2017)The large number of protein structures deposited in the protein database provide an opportunity to examine the structure relations using computational algorithms, which can be used to classify the structures based on shape ... -
Protein Shape Retrieval Contest
(The Eurographics Association, 2019)This track aimed at retrieving protein evolutionary classification based on their surfaces meshes only. Given that proteins are dynamic, non-rigid objects and that evolution tends to conserve patterns related to their ... -
Quantitative Comparison of Hole Filling Methods for 3D Object Search
(The Eurographics Association, 2014)Retrieval of 3D models has become an important issue due to the increase in the number of digitized objects that are available in many different fields. When stored data present defects such as holes, accurate and reliable ... -
Randomized Sub-Volume Partitioning for Part-Based 3D Model Retrieval
(The Eurographics Association, 2015)Given a query that specifies partial shape, a Part-based 3D Model Retrieval (P3DMR) system would retrieve 3D models whose part(s) matches the query. Computationally, this is quite challenging; the query must be compared ... -
Range Scans based 3D Shape Retrieval
(The Eurographics Association, 2015)The objective of the SHREC'15 Range Scans based 3D Shape Retrieval track is to evaluate algorithms that match range scans of real objects to complete 3D mesh models in a target dataset. The task is to retrieve a rank list ... -
