TreeSha: 3D Shape Retrieval with a Tree Graph Representation based on the Autodiffusion Function Topology
(The Eurographics Association, 2014)
In this paper we present a new method for shape description and matching based on a tree representation built upon the scale space analysis of maxima of the Autodiffusion function (ADF). The use of the Heat Kernel based ...
Fisher Encoding of Adaptive Fast Persistent Feature Histograms for Partial Retrieval of 3D Pottery Objects
(The Eurographics Association, 2014)
Cultural heritage is a natural application domain for partial 3D object retrieval, since it usually involves objects that have only been partially preserved. This work introduces a method for the retrieval of 3D pottery ...
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 ...
Manifold Harmonic Transform and Spatial Relationships for Partial 3D Object Retrieval
(The Eurographics Association, 2014)
This paper presents an approach for 3D object retrieval, dedicated to partial shape retrieval in large datasets. A word manipulation, i.e. quantized descriptors, as in the Bag-of-Words representation is employed, based on ...
GeoTopo: Dynamic 3D Facial Expression Retrieval Using Topological and Geometric Information
(The Eurographics Association, 2014)
Recently, a lot of research has been dedicated to address the problem of facial expression recognition in dynamic sequences of 3D face scans. On the contrary, no research has been conducted on facial expression retrieval ...
Symmetry and Fourier Descriptor: A Hybrid Feature For NURBS based B-Rep Models Retrieval
(The Eurographics Association, 2014)
As the number of models in 3D databases grows, an efficient 3D models indexing mechanism and a similarity measure to ease model retrieval are necessary. In this paper, we present a query-by-model framework for NURBS based ...
Similarity of Deforming Meshes Based on Spatio-temporal Segmentation
(The Eurographics Association, 2014)
In this study, we investigate a similarity metric for comparing two deforming meshes. While there have been a large body of works on computing the similarity of static shapes, similarity judgments on deforming meshes are ...
Coulomb Shapes: Using Electrostatic Forces for Deformation-invariant Shape Representation
(The Eurographics Association, 2014)
Canonical shape analysis is a popular method in deformable shape matching, trying to bring the shape into a canonical form that undoes its non-rigid deformations, thus reducing the problem of non-rigid matching into a rigid ...
Retrieval and Classification on Textured 3D Models
(The Eurographics Association, 2014)
This paper reports the results of the SHREC'14 track: Retrieval and classification on textured 3D models, whose goal is to evaluate the performance of retrieval algorithms when models vary either by geometric shape or ...
Towards the Extraction of Hierarchical Building Descriptions from 3D Indoor Scans
(The Eurographics Association, 2014)
We present a new method for the hierarchical decomposition of 3D indoor scans and the subsequent generation of an according hierarchical graph-based building descriptor. The hierarchy consists of four basic levels with ...
