Guiding Lens-based Exploration using Annotation Graphs
(The Eurographics Association, 2021)
We introduce a novel approach for guiding users in the exploration of annotated 2D models using interactive visualization lenses. Information on the interesting areas of the model is encoded in an annotation graph generated ...
Evaluating Deep Learning Methods for Low Resolution Point Cloud Registration in Outdoor Scenarios
(The Eurographics Association, 2021)
Point cloud registration is a fundamental task in 3D reconstruction and environment perception. We explore the performance of modern Deep Learning-based registration techniques, in particular Deep Global Registration (DGR) ...
Efficient Image Vectorisation Using Mesh Colours
(The Eurographics Association, 2021)
Image vectorisation methods proposed in the past have not seen wide adoption due to performance, quality, controllability, and/or generality issues.We present a vectorisation method that uses mesh colours as a vector ...
STRONGER: Simple TRajectory-based ONline GEsture Recognizer
(The Eurographics Association, 2021)
In this paper, we present STRONGER, a client-server solution for the online gesture recognition from captured hands' joints sequences. The system leverages a CNN-based recognizer improving current state-of-the-art solutions ...
3D City Reconstruction from OpenStreetMap Data
(The Eurographics Association, 2021)
Virtual city generation from real data is far from being straightforward for users, as it strictly depends on the application domain, amount of information available, and the adopted reconstruction techniques. Nowadays, ...
SlowDeepFood: a Food Computing Framework for Regional Gastronomy
(The Eurographics Association, 2021)
Food computing recently emerged as a stand-alone research field, in which artificial intelligence, deep learning, and data science methodologies are applied to the various stages of food production pipelines. Food computing ...
IMGD: Image-based Multiscale Global Descriptors of Airborne LiDAR Point Clouds Used for Comparative Analysis
(The Eurographics Association, 2021)
Both geometric and semantic information are required for a complete understanding of regions acquired as three-dimensional (3D) point clouds using the Light Detection and Ranging (LiDAR) technology. However, the global ...
Exploring Upper Limb Segmentation with Deep Learning for Augmented Virtuality
(The Eurographics Association, 2021)
Sense of presence, immersion, and body ownership are among the main challenges concerning Virtual Reality (VR) and freehand-based interaction methods. Through specific hand tracking devices, freehand-based methods can allow ...
Mesh Colours for Gradient Meshes
(The Eurographics Association, 2021)
We present an extension of the popular gradient mesh vector graphics primitive with the addition of mesh colours, aiming to reduce the mesh complexity needed to describe intricate colour gradients and textures. We present ...
Reposing and Retargeting Unrigged Characters with Intrinsic-extrinsic Transfer
(The Eurographics Association, 2021)
In the 3D digital world, deformations and animations of shapes are fundamental topics for several applications. The entertainment industry, virtual and augmented reality, human-robot interactions are just some examples ...
