Real-time Expression Recognition from Dynamic Sequences of 3D Facial Scans
(The Eurographics Association, 2012)
In this paper, we address the problem of person-independent facial expression recognition in dynamic sequences of 3D face scans. To this end, an original approach is proposed that relies on automatically extracting a set ...
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 ...
Geometric Histograms of 3D Keypoints for Face Identification with Missing Parts
(The Eurographics Association, 2013)
In this work, an original solution to 3D face identification is proposed, which supports recognition also in the case of probes with missing parts. Distinguishing traits of the face are captured by first extracting 3D ...
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, ...
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 ...
Face Recognition by SVMs Classification and Manifold Learning of 2D and 3D Radial Geodesic Distances
(The Eurographics Association, 2008)
An original face recognition approach based on 2D and 3D Radial Geodesic Distances (RGDs), respectively computed on 2D face images and 3D face models, is proposed in this work. In 3D, the RGD of a generic point of a 3D ...
Computing Local Binary Patterns on Mesh Manifolds for 3D Texture Retrieval
(The Eurographics Association, 2015)
In this paper, we present and experiment a novel approach for retrieving 3D geometric texture patterns on 2D mesh-manifolds (i.e., surfaces in the 3D space) using local binary patterns (LBP) constructed on the mesh. The ...
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 ...
SHREC 2020 Track: River Gravel Characterization
(The Eurographics Association, 2020)
The quantitative analysis of the distribution of the different types of sands, gravels and cobbles shaping river beds is a very important task performed by hydrologists to derive useful information on fluvial dynamics and ...
Eurographics Workshop on 3D Object Retrieval - Short Papers: Frontmatter
