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 ...
Completion of Cultural Heritage Objects with Rotational Symmetry
(The Eurographics Association, 2018)
Archaeological artifacts are an important part of our cultural heritage. They help us understand how our ancestors used to live. Unfortunately, many of these objects are badly damaged by the passage of time and need repair. ...
Automatic Extraction of Complex 3D Structures Application to the Inner Ear Segmentation from Cone Beam CT Digital Volumes
(The Eurographics Association, 2018)
We present an automatic approach for the retrieval of a complex structure within a 3D digital volume, using a generic deformable surface model. We apply this approach to the inner ear reconstruction of Cone Beam CT(CBCT) ...
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, ...
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 ...
mpLBP: An Extension of the Local Binary Pattern to Surfaces based on an Efficient Coding of the Point Neighbours
(The Eurographics Association, 2019)
The description of surface textures in terms of repeated colorimetric and geometric local surface variations is a crucial task for several applications, such as object interpretation or style identification. Recently, ...
Generalizing Discrete Convolutions for Unstructured Point Clouds
(The Eurographics Association, 2019)
Point clouds are unstructured and unordered data, as opposed to images. Thus, most of machine learning approaches, developed for images, cannot be directly transferred to point clouds. It usually requires data transformation ...
CMH: Coordinates Manifold Harmonics for Functional Remeshing
(The Eurographics Association, 2019)
In digital world reconstruction, 2-dimensional surface of real objects are often obtained as polygonal meshes after an acquisition procedure using 3D sensors. However, such representation requires several manual efforts ...
Depth-Based Face Recognition by Learning from 3D-LBP Images
(The Eurographics Association, 2019)
In this paper, we propose a hybrid framework for face recognition from depth images, which is both effective and efficient. It consists of two main stages: First, the 3DLBP operator is applied to the raw depth data of the ...
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 ...
