Mutual Correspondences: An Hybrid Method for Image-to-geometry Registration
(The Eurographics Association, 2010)
Image registration is an important task in several applications of Computer Graphics and Computer Vision. Among the large number of proposed approaches, currently there is no solution which is automatic and robust enough ...
A Low-Memory, Straightforward and Fast Bilateral Filter Through Subsampling in Spatial Domain
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
In this work we present a new algorithm for accelerating the colour bilateral filter based on a subsampling strategy working in the spatial domain. The base idea is to use a suitable subset of samples of the entire kernel ...
Design and Fabrication of Grid-shells Mockups
(The Eurographics Association, 2016)
Statics Aware Voronoi Grid-shells have been recently introduced in the Architectural Geometry field. These are innovative gridshells endowed with a polygonal topology, whose geometry is structurally optimized by means of ...
Generalized Trackball for Surfing Over Surfaces
(The Eurographics Association, 2016)
We present an efficient 3D interaction technique: generalizing the well known trackball approach, this technique unifies and blends the two common interaction mechanisms known as panning and orbiting. The approach allows ...
Detection of Geometric Temporal Changes in Point Clouds
(Copyright © 2016 The Eurographics Association and John Wiley & Sons Ltd., 2016)
Detecting geometric changes between two 3D captures of the same location performed at different moments is a critical operation for all systems requiring a precise segmentation between change and no‐change regions. Such ...
Tracing Field-Coherent Quad Layouts
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Given a cross field over a triangulated surface we present a practical and robust method to compute a field aligned coarse quad layout over the surface. The method works directly on a triangle mesh without requiring any ...
Statics Aware Grid Shells
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We introduce a framework for the generation of polygonal grid-shell architectural structures, whose topology is designed in order to excel in static performances. We start from the analysis of stress on the input surface ...
Joint Interactive Visualization of 3D Models and Pictures in Walkable Scenes
(The Eurographics Association, 2012)
The 3D digitalization of buildings, urban scenes, and the like is now a mature technology. Highly complex, densely sampled, reasonably accurate 3D models can be obtained by range-scanners and even image-based reconstruction ...
A computer-assisted constraint-based system for assembling fragmented objects
(The Eurographics Association, 2013)
We propose a computer-assisted constraint-based methodology for virtual reassembly of Cultural Heritage (CH) artworks. Instead than focusing on automatic, unassisted reassembly, we targeted the scenarios where the ...
Surface Light Field from Video Acquired in Uncontrolled Settings
(The Eurographics Association, 2013)
This paper presents an algorithm for the estimation of the Surface Light Field using video sequences acquired moving the camera around the object. Unlike other state of the art methods, it does not require a uniform sampling ...
