Towards the Creation of Digital Stones from 2D Samples
(The Eurographics Association, 2014)
In order to decide which preservation strategies one should follow for Cultural Heritage objects made of stone, it is necessary to estimate the impact of different alternative strategies. A useful aid in such a process is ...
Template-Based 3D Non-Rigid Shape Estimation from Monocular Image Sequences
(The Eurographics Association, 2017)
This paper addresses the problem of reconstructing non-rigid 3D geometries from temporal image sequences captured with only a single camera under full perspective projection. Without the knowledge of a shape deformation ...
Bezier Crust on Quad Subdivision Surface
(The Eurographics Association, 2013)
Subdivision surfaces have been widely used in computer graphics and can be classified into two categories, approximating and interpolatory. Representative approximating schemes are Catmull-Clark (quad) and Loop (triangular). ...
An Effective Condition for Sampling Surfaces with Guarantees
(The Eurographics Association, 2004)
The notion of e-sample, as introduced by Amenta and Bern, has proven to be a key concept in the theory of sampled surfaces. Of particular interest is the fact that, if E is an e-sample of a smooth surface S for a suf ciently ...
Medial Axis Extraction and Shape Manipulation of Solid Objects Using Parabolic PDEs
(The Eurographics Association, 2004)
Shape skeletonization (i.e., medial axis extraction) is powerful in many visual computing applications, such as pattern recognition, object segmentation, registration, and animation. This is because medial axis (or skeleton) ...
Efficient Breast Deformation Simulation
(The Eurographics Association, 2012)
Breast surgery might benefit from image guidance, if position and extend of the disease could be visualized in the same breast deformation as the surgery is performed. Such visualizations, however, are challenging to obtain, ...
Euler Operators for Stratified Objects with Incomplete Boundaries
(The Eurographics Association, 2004)
Stratified objects such as those found in geometry-based systems (e.g. CAD systems and animation systems) can be stepwise constructed and manipulated through Euler operators. The operators proposed in this paper extend ...
Resolving Twisted Surfaces within an Iterative Refinement Surface Reconstruction Approach
(The Eurographics Association, 2012)
We present a method which resolves twisted surface regions within a surface reconstruction approach that uses local refinement operations to iteratively fit a surface into an unorganized point cloud. We show that this local ...
Plumber: A Multi-scale Decomposition of 3D Shapes into Tubular Primitives and Bodies
(The Eurographics Association, 2004)
Plumber is a specialized shape classi cation method for detecting tubular features of 3D objects represented by a triangle mesh. The Plumber algorithm segments a surface into connected components that are either body parts ...
Non-rigid 3D Shape Retrieval via Sparse Representation
(The Eurographics Association, 2013)
Shape descriptor design is an important but challenging problem for non-rigid 3D shape retrieval. Recently, bagof- words based methods are widely used to integrate a model's local shape descriptors into a global histogram. ...
