In collaborative VR it also facilitates non-verbal communication. Currently it is possible to track a few body parts with cheap trackers and then apply IK methods to animate a character. However, the correspondence between trackers and avatar joints is typically fixed ad-hoc, which is enough to animate the avatar, but causes noticeable mismatches between the user's body pose and the avatar. In this paper we present a fast and easy to set up system to compute exact offset values, unique for each user, which leads to improvements in avatar movement. Our user study shows that the Sense of Embodiment increased significantly when using exact offsets as opposed to fixed ones. We also allowed the users to see a semitransparent avatar overlaid with their real body to objectively evaluate the quality of the avatar movement with our technique.","PeriodicalId":72958,"journal":{"name":"Eurographics ...

However, 3DMM fitting on infants is a largely unexplored problem. All publicly available 3DMMs are developed for adults, and it is unclear if and to what extent they can be used on videos of infants. In this paper, we compare five state-of-the-art 3DMM fitting methods on data from naturalistic infant-caregiver interactions. Results suggest that it is possible to produce consistent and subject-specific reconstructions of 3D shape identity from multiple frames, but not from a single frame. Qualitative evaluation highlights that facial regions with high texture variation, such as eyes, brows and mouth, are captured with higher accuracy compared to the rest of the face. Thus, even though a 3DMM developed for adults has significant limitations when reconstructing the morphology of the entire facial region of infants, applications that involve analysis of facial behavior can be feasible. Our encouraging results, combined with the unique ability of 3DMMs to disentangle two major sources of noise for expression analysis (i.e., identity bias and pose variations), motivate future research on using 3DMMs to measure the facial behavior of infants.</p>","PeriodicalId":72958,"journal":{"name":"Eurographics ...

The exhibition entrance sits directly across from Sean Scully’s The Moroccan (1984), positioning White Hawk’s work as a commentary on the Euro-American appropriation of non-white aesthetics. See for example, her canvas Untitled (coral, turquoise, and yellow) (2016), which embeds intricate rows of blue and yellow beads within bands of orange and red paint that evoke colour field painting. White Hawk receives pride of place in the museum’s main exhibition space, a series of four rooms showcasing the artist’s skill in many media: acrylic painting, beadwork, video, and photography. She layers and leverages Indigenous motifs amidst those associated with Euro-American artists. The exhibition tackles the debate over the false binary of art vs. craft and the centrality of indigenous women to Native American communities; the exhibition tackles the former deftly, the latter feels less fully explored.","PeriodicalId":72958,"journal":{"name":"Eurographics ...

Fluidity is distinct from liquidity in that it presents a process of transition from solid to liquid in the case of Liquid Crystal Environment and liquid to gas in Condensation Cube. The stakes of this fluid process are, as I argue, crucial to understanding the critical stakes of these works in relation to Haacke and Metzger's artistic practise. By examining fluid process, I hope to show how these early pieces also contribute institutional and political criticisms that are typically associated with Haacke and Metzger's later work.","PeriodicalId":72958,"journal":{"name":"Eurographics ...

Within the country’s post-revolutionary Directory and Consulate epoch, Récamier ran a salon that boasted prominent political figures and writers among its frequent guests. Récamier’s own legacy however is one of seemingly total passivity: praise aside, the impression we are left with is one of placid docility. Récamier was greatly admired, yet incapable of articulating her own thoughts and ideas. This article examines François Gérard’s portrait of Récamier. At the time, Gérard (1770-1837) was one of the period’s most successful artists, whose services Napoléon would request for his coronation portrait in 1805. Gérard’s work leads to this study’s argument that the articulation and presentation of self image in the early nineteenth century was no less layered and complex than the creation of material images. In fact, it illustrates just how much Gérard’s portrait is an image of her making as much as it is of his. We see such agency further mediated in Récamier’s shawl dance, a performative staple of the soirées she hosted. Imbuing the artistic virtues associated with neoclassical dress with the passion, sensuality, and individualistic nature of dance; this article considers Récamier’s self-fashioning on a stage exclusively within her salon.","PeriodicalId":72958,"journal":{"name":"Eurographics ...

We leverage the power of neural networks to inject the underlying shape geometry into the deformation parameters. The goal of our technique is to enable a realistic and intuitive shape deformation. Our method is built upon moving least-squares (MLS), since it minimizes a weighted sum of the given control point displacements. Traditionally, the influence of each control point on every point in space (i.e., the weighting function) is defined using inverse distance heuristics. In this work, we opt to learn the weighting function, by training a neural network on the control points from a single input shape, and exploit the innate smoothness of neural networks. Our geometry-aware control point deformation is agnostic to the surface representation and quality; it can be applied to point clouds or meshes, including non-manifold and disconnected surface soups. We show that our technique facilitates intuitive piecewise smooth deformations, which are well suited for manufactured objects. We show the advantages of our approach compared to existing surface and space-based deformation techniques, both quantitatively and qualitatively.","PeriodicalId":72958,"journal":{"name":"Eurographics ...

Furthermore, we show that discarding already visited regions of neighboring mip texels widens the obtained cones considerably while still being conservative.

Recent advances leverage additional knowledge that is not available in all contexts, i.e., known shape or depth information from a sensor. General-purpose machine learning models, that do not utilize such additional knowledge, have not yet been explicitly evaluated regarding their performance on transparent structures. In this work, we show that these models show poor performance on the depth estimation of transparent structures. However, fine-tuning on suitable data sets, such as ClearGrasp, increases their estimation performance on the task at hand. Our evaluations show that high performance on general-purpose benchmarks translates well into performance on transparent objects after fine-tuning. Furthermore, our analysis suggests, that state-of-theart high-performing models are not able to capture a high grade of detail from both the image foreground and background at the same time. This finding shows the demand for a combination of existing models to further enhance depth estimation quality.
