For typical feature definitions, such as vortices, objects are sparsely distributed over the data domain. In this paper, we present a novel approach for tracking both sparse and space-filling features. While the former comprise only a small fraction of the domain, the latter form a set of objects whose union covers the domain entirely while the individual objects are mutually disjunct. Our approach determines the assignment of features between two successive time-steps by solving two graph optimization problems.

However, unstructured grids often lead to complicated implementations and a poor cache hit rate due to inconsistent memory access. Regular grids, on the other hand, provide a fast, fixed memory access pattern and straightforward implementation. Our method combines the advantages of both: we leverage the simplicity of regular grids while still achieving practical and controllable spatial adaptivity. We demonstrate that our method enables adaptive simulations that are fast, flexible, and robust to null-space issues.

In this article, we describe a new approach to video-based augmented reality that avoids both requirements: It does not use any metric information about the calibration parameters of the camera or the 3D locations and dimensions of the environment's objects. The only requirement is the ability to track across frames at least four fiducial points that are specified by the user during system initialization and whose world coordinates are unknown.Our approach is based on the following observation: Given a set of four or more noncoplanar 3D points, the projection of all points in the set can be computed as a linear combination of the projections of just four of the points. We exploit this observation by 1) tracking regions and color fiducial points at frame rate, and 2) representing virtual objects in a non-Euclidean, affine frame of reference that allows their projection to be computed as a linear combination of the projection of the fiducial points.

To address these issues, Splatterplots abstract away information such that the density of data shown in any unit of screen space is bounded, while allowing continuous zoom to reveal abstracted details.

We build upon the ideas of the density maps approach which has been introduced recently by Koschier and Bender. They precompute the density contributions of solid boundaries and store them on a spatial grid which can be efficiently queried during runtime. This alleviates the problems of commonly used boundary particles, like bumpy surfaces and inaccurate pressure forces near boundaries. Our method is based on a similar concept but we precompute the volume contribution of the boundary geometry. This maintains all benefits of density maps but offers a variety of advantages which are demonstrated in several experiments. First, in contrast to the density maps method we can compute derivatives in the standard SPH manner by differentiating the kernel function. This results in smooth pressure forces, even for lower map resolutions, such that precomputation times and memory requirements are reduced by more than two orders of magnitude compared to density maps. Furthermore, this directly fits into the SPH concept so that volume maps can be seamlessly combined with existing SPH methods. Finally, the kernel function is not baked into the map such that the same volume map can be used with different kernels. This is especially useful when we want to incorporate common surface tension or viscosity methods that use different kernels than the fluid simulation.", "abstracts": [ { "abstractType": "Regular", "content": "In this article, we present a novel method for the robust handling of static and dynamic rigid boundaries in Smoothed Particle Hydrodynamics (SPH) simulations.

In order to achieve real-time performance, multiple operations are processed in a synchronized multi-threaded manner: capturing a video frame, tracking features using optical flow, detecting distinctive invariant features, and rendering an output frame. We also introduce user interaction methodology for establishing a global coordinate system and for placing virtual objects in the AR environment by tracking a user's outstretched hand and estimating a camera pose relative to it. We evaluate the speed and accuracy of our hybrid feature tracking approach, and demonstrate a proof-of-concept application for enabling AR in unprepared tabletop environments, using bare hands for

The Teichmuller space for surfaces with the same topology is a finite dimensional manifold, where each point represents a conformal equivalence class, a curve represents a deformation process from one class to the other. We apply Teichmuller space coordinates as shape descriptors, which are succinct, discriminating and intrinsic; invariant under the rigid motions and scalings, insensitive to resolutions. Furthermore, the method has solid theoretic foundation, and the computation of Teichmuller coordinates is practical, stable and efficient. This work focuses on the surfaces with negative Euler numbers, which have a unique conformal Riemannian metric with -1 Gaussian curvature. The coordinates which we will compute are the lengths of a special set of geodesics under this special metric. The metric can be obtained by the curvature flow algorithm, the geodesics can be calculated using algebraic topological method. We tested our method extensively for indexing and comparison of about one hundred of surfaces with various topologies, geometries and resolutions.

We introduce two new interaction concepts: Higher-order, sketch-based brushing, and smart, data-driven brushing. Higher-order brushes support interactive, flexible, n-dimensional pattern searches involving an arbitrary number of dimensions. Smart, data-driven brushing provides interactive, real-time guidance to the user during the brushing process based on derived meta-data. In addition, we implement a selection of novel enhancements and user options that complement the two techniques as well as enhance the exploration and analytical ability of the user. We demonstrate the utility and evaluate the results using a case study with a large, high-dimensional, real-world telecommunication data set and we report domain expert feedback from the data suppliers.", "title": "Smart Brushing for Parallel Coordinates", "normalizedTitle": "Smart Brushing for Parallel Coordinates", "fno": "08302598", "hasPdf": true, "idPrefix": "tg", "keywords": [ "Data Visualisation", "Real World Telecommunication Data Set", "Data Suppliers", "Parallel Coordinates Plot", "High Dimensional Data", "Visual Design", "Smart Brushing Techniques", "Standard Interactive Brushing", "Interaction Concepts", "Sketch Based Brushing", "Smart Data Driven Brushing", "N Dimensional Pattern Searches", "Brushing Process", "Brushes", "Data Visualization", "Visualization", "Communications Technology", "Industries", "Tools", "Standards", "Multivariate Visualization", "Parallel Coordinates", "Call Center", "Glyph", "Brushing", "Interaction Techniques" ], "authors": [ { "givenName": "Richard C.", "surname": "Roberts", "fullName": "Richard C.

The surrounding lighting information estimated by our method ensures coherent illumination of 3D objects blended with the input photograph, enabling high fidelity augmented and mixed reality supporting a wide range of environmental lighting conditions and device sensors.", "__typename": "ArticleAbstractType" } ], "normalizedAbstract": "High dynamic range (HDR) panoramic environment maps are widely used to illuminate virtual objects to blend with real-world scenes. However, in common applications for augmented and mixed-reality (AR/MR), capturing 360° surroundings to obtain an HDR environment map is often not possible using consumer-level devices. We present a novel light estimation method to predict 360° HDR environment maps from a single photograph with a limited field-of-view (FOV). We introduce the Dynamic Lighting network (DLNet), a convolutional neural network that dynamically generates the convolution filters based on the input photograph sample to adaptively learn the lighting cues within each photograph. We propose novel Spherical Multi-Scale Dynamic (SMD) convolutional modules to dynamically generate sample-specific kernels for decoding features in the spherical domain to predict 360° environment maps. Using DLNet and data augmentations with respect to FOV, an exposure multiplier, and color temperature, our model shows the capability of estimating lighting under diverse input variations. Compared with prior work that fixes the network filters once trained, our method maintains lighting consistency across different exposure multipliers and color temperature, and maintains robust light estimation accuracy as FOV increases.

Using a mobile device equipped with an embedded RGBD camera, our system provides online 3D object reconstruction capability for users to acquire high-quality textured 3D object models. Starting with a simultaneous pose tracking and TSDF fusion module, our system allows users to scan an object with a mobile device to get a 3D model for real-time preview. After the real-time scanning process is completed, the scanned 3D model is globally optimized and mapped with multi-view textures as an efficient postprocess to get the final textured 3D model on the mobile device. Unlike most existing state-of-the-art systems which can only scan homeware objects such as toys with small dimensions due to the limited computation and memory resources of mobile platforms, our system can reconstruct objects with large dimensions such as statues. We propose a novel visual-inertial ICP approach to achieve real-time accurate 6DoF pose tracking of each incoming frame on the front end, while maintaining a keyframe pool on the back end where the keyframe poses are optimized by local BA.
