An Automatic Approach for the Classification of Ancient Clay Statuettes Based on Heads Features Recognition
(The Eurographics Association, 2019)
In recent years, quantitative approaches based on mathematical theories and ICT tools, known under the terms of digital, computational, and virtual archaeology, are more and more involved in the traditional archaeological ...
UI-Net: Interactive Artificial Neural Networks for Iterative Image Segmentation Based on a User Model
(The Eurographics Association, 2017)
For complex segmentation tasks, fully automatic systems are inherently limited in their achievable accuracy for extracting relevant objects. Especially in cases where only few data sets need to be processed for a highly ...
Soft Finger-tip Sensing Probe Based on Haptic Primary Colors
(The Eurographics Association, 2018)
This paper describes a novel tactile sensing probe based on haptic primary colors (HPCs) and a tactile classifying system. We developed a finger-type soft tactile probe incorporating a sensor to measure three physical ...
Individualized Calibration of Rotation Gain Thresholds for Redirected Walking
(The Eurographics Association, 2018)
Redirected walking allows the exploration of large virtual environments within a limited physical space. To achieve this, redirected walking algorithms must maximize the rotation gains applied while remaining imperceptible ...
Towards an Automatic 3D Patterns Classification: the GRAVITATE Use Case
(The Eurographics Association, 2018)
When cataloging archaeological fragments, decorative patterns are an indicator of the stylistic canon an object belongs to. In this paper we address a quantitative classification of the decorative pattern elements that ...
A Primal-to-Primal Discretization of Exterior Calculus on Polygonal Meshes
(The Eurographics Association, 2017)
Discrete exterior calculus (DEC) offers a coordinate-free discretization of exterior calculus especially suited for computations on curved spaces. We present an extended version of DEC on surface meshes formed by general ...
Reproduction of Gloss, Color and Relief of Paintings using 3D Scanning and 3D Printing
(The Eurographics Association, 2017)
High fidelity reproductions of paintings provide new opportunities to museums in preserving and providing access to cultural heritage. This paper presents an integrated system which is able to capture and fabricate color, ...
Random-Forest-Based Initializer for Real-time Optimization-based 3D Motion Tracking Problems
(The Eurographics Association, 2019)
Many motion tracking systems require solving inverse problem to compute the tracking result from original sensor measurements, such as images from cameras and signals from receivers. For real-time motion tracking, such ...
An Efficient Denoising Algorithm for Global Illumination
(ACM, 2017)
We propose a hybrid ray-tracing/rasterization strategy for real- time rendering enabled by a fast new denoising method. We factor global illumination into direct light at rasterized primary surfaces and two indirect lighting ...
An Image-based Approach for Detecting Faces Carved in Heritage Monuments
(The Eurographics Association, 2018)
Heritage monuments such as columns, memorials and buildings are typically carved with a variety of visual features, including figural content, illustrating scenes from battles or historical narratives. Understanding such ...
