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 ...
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 ...
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 ...
LightNet: A Lightweight 3D Convolutional Neural Network for Real-Time 3D Object Recognition
(The Eurographics Association, 2017)
With the rapid growth of 3D data, accurate and efficient 3D object recognition becomes a major problem. Machine learning methods have achieved the state-of-the-art performance in the area, especially for deep convolutional ...
Sketch-based Image-independent Editing of 3D Tumor Segmentations using Variational Interpolation
(The Eurographics Association, 2012)
In the past years sophisticated automatic segmentation algorithms for various medical image segmentation problems have been developed. However, there are always cases where automatic algorithms fail to provide an acceptable ...
Creating Contour Gradients using 3D Bevels
(ACM, 2013)
Contour gradients have color contours that follow the shape of the path being filled. Existing algorithms cannot create them in a resolution- and scale-independent way, causing visible rendering artifacts if enlarged. We ...
Mesh Statistics for Robust Curvature Estimation
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
While it is usually not difficult to compute principal curvatures of a smooth surface of sufficient differentiability, it is a rather difficult task when only a polygonal approximation of the surface is available, because ...
CubeCover - Parameterization of 3D Volumes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Despite the success of quad-based 2D surface parameterization methods, effective parameterization algorithms for 3D volumes with cubes, i.e. hexahedral elements, are still missing. CUBECOVER is a first approach for generating ...
Surface Patches from Unorganized Space Curves
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Recent 3D sketch tools produce networks of three-space curves that suggest the contours of shapes. The shapes may be non-manifold, closed three-dimensional, open two-dimensional, or mixed. We describe a system that ...
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 ...
