Effects of virtual agent and object representation on experiencing exhibited artifacts
Highlights

  • Virtual embodied guides elicit a higher sense of spatial as well as social presence and appear more credible to users than virtual audio guides.

Abstract

With the emergence of speech-controlled virtual agents (VAs) in consumer devices such as Amazon’s Echo or Apple’s HomePod, we have seen a large public interest in related technologies. While most of the current interactive ...

Abstract

In this paper, we describe two human-subject studies in which we explored and investigated the effects of subtle multimodal interaction on social presence with a virtual human (VH) in mixed reality (MR). In the studies, participants ...

Intelligent interaction and uncertainty visualization for efficient drusen and retinal layer segmentation in Optical Coherence Tomography
Highlights

  • Developed semi-automated tools for correcting retinal layer and drusen segmentation.

Graphical abstract

Abstract

Convolutional neural networks (CNNs) represent the state of the art for fully automated medical image segmentation. However, few works have combined CNNs with interactive user feedback in order to verify and, where necessary, correct ...

Visual analysis of regional myocardial motion anomalies in longitudinal studies
Highlights

  • Early detection of regional anomalies in myocardial motion for patients after the heart-transplant operation.

Graphical abstract

Display Omitted

Abstract

A heart-transplanted patient is at risk of developing several complications such as rejection, which is one of the leading causes of deaths in the first year after the transplant. The regional myocardial motion is known to be depressed ...

Voxel-based edge bundling through direction-aware kernel smoothing
Highlights

  • The 10k edges represented in 10k voxels still allow for an interactive analysis.

Graphical abstract

Abstract

Relational data with a spatial embedding and depicted as node-link diagram is very common, e.g, in neuroscience, and edge bundling is one way to increase its readability or reveal hidden structures. This article presents a 3D extension ...

Automatic extraction and synthesis of regular repeatable patterns
Highlights

  • Automatic method capable of synthesizing regular repeating patterns in images.
  • ...

Graphical abstract

Abstract

Textures made of regular repeating patterns are ubiquitous in the real world, most notably in man-made environments. They are defined by the presence of a repeating element, which can show a significant amount of random variations, non-...

Abstract

Photographers use the hardware of the camera (aperture, exposure time...), lens and filters as tools for artistic expressivity. This expressivity has often been enhanced by software, such as high dynamic range images have been edited ...

A visually realistic grasping system for object manipulation and interaction in virtual reality environments
Highlights

  • A novel, robust and flexible grasping system for real-time interaction in VR.
  • ...

Graphical abstract

Fast collision detection between high resolution polygonal models
Highlights

  • We use the EBP-Octree data structure to detect colliding triangles very complex scenarios.

Graphical abstract

Display Omitted

Abstract

In this paper, we address the problem of collision detection between very high resolution polygonal models. We propose an approach that uses the EBP-Octree data structure in a single-core CPU architecture. The algorithm manages a set ...

Transient instant radiosity for efficient time-resolved global illumination
Highlights

  • We generalize the classic work of instant radiosity, which is very suitable for parallelism in the GPU, to transient state.

Graphical abstract

Abstract

Over the last decade, transient imaging has had a major impact in the area of computer graphics and computer vision. The hability of analyzing light propagation at picosecond resolution has enabled a variety of applications such as non-...
