Improvement of some interpolation methods for terrain reconstruction from scattered data

Using GPS modules it is easy to obtain 3D data for areas that have not been digitized yet. Such terrain data are usually not arranged in a grid, and therefore we have to use scattered data interpolation methods. The aim of the paper is to create a di...

Pushpins for edit propagation

In this paper we present an approach for stroke-input based foreground estimation of measured materials with a near regular structure. To enable extraction of high-quality editing masks even from difficult materials, we combine a state of the art lattice-detection algorithm with a novel...

StreetGAN: towards road network synthesis with generative adversarial networks

We propose a novel example-based approach for road network synthesis relying on Generative Adversarial Networks (GANs), a recently introduced deep learning technique. In a pre-processing step, we first convert a given representation of a road network patch into a binary image where pixe...

Fast and effective dynamic mesh completion

We introduce a novel approach to support fast and efficient completion of arbitrary animation sequences, ideally suited for real-time scenarios, such as immersive tele-presence systems and gaming. In most of these applications, the reconstruction of 3D animations is based on dynamic meshes&#...

iDotter: an interactive dot plot viewer

Bioinformaticians judge the likelihood of the overall RNA secondary structure based on comparing its base pair probabilities. These probabilities can be calculated by various tools and are frequently displayed using dot plots for further analysis. However, most tools produce only static dot&...

Accurate triangular regular network adjustment to large digital elevation models

Nowadays, large volumes of terrain data are available to use as Digital Elevation Models, from which coarser meshes can be progressively generated for visualization and other purposes. Previous studies compared different methods to adjust those meshes, concluding that no method performs the&...

Accelerating radiosity on GPUs

We propose a novel approach to implement radiosity on GPU with specific optimizations via form-factor matrix transformations. The proposed transformations enable to reduce the amount of computations for multiple-bounce global illumination and apply DXT compression (with subsequent hardware decompression&#x...

Head movement based temporal antialiasing for VR HMDs

Inherent properties of VR HMDs cause degradation of visual quality which disrupts immersive VR experience. We identify a new temporal aliasing problem caused by unintended tiny head movement of VR HMD users. The images that users see slightly change, even in the case that the&...

Marine snow detection and removal: underwater image restoration using background modeling

It is a common problem that images captured underwater (UW) are corrupted by noise. This is due to the light absorption and scattering by the marine environment; therefore, the visibility distance is limited up to few meters. Despite blur, haze, low contrast, non-uniform lightening...

Speeding up the computation of uniform bicubic spline surfaces

Approximation of surfaces plays a key role in a wide variety of computer science fields such as graphics or CAD applications. Recently a new algorithm for evaluation of interpolating spline surfaces with C2 continuity over uniform grids was proposed based on a special approximation...

Predicting vehicle trajectories from surveillance video in a real scenario with Histogram of Oriented Gradient

We propose a method capable to predict vehicle trajectories in a real scenario based on an unsupervised approach using Histogram of Oriented Gradients (HOG) features to construct an uniform path. The proposed algorithm extracts a sub-region of the input image defined as Field of&#x...

A primary morphological classifier for skin lesion images

Classifying skin lesions, abnormal changes in skin, into their morphologies is the first step in diagnosing skin diseases. In dermatology, morphology is a categorization of a skin lesion’s structure and appearance. Rather than directly classifying skin diseases, this research aims to explore...

A generic approach for sunlight and shadow impact computation on large city models

Study of sunlight and shadow effects on the city has become more accessible with the development of 3D city models. It allows measuring when and how an object is exposed to the sunlight, which enables conducting many related studies such as energy analyses or urban planni...

A novel force feedback haptics system with applications in phobia treatment

It is well known that multi-sensory stimulation can enhance immersion within virtual environments. Whilst there has been rapid development of devices which can enhance the visual immersion, technology to stimulate other senses, such as touch, is still under developed. Currently there is ...

A framework for visually realistic multi-robot simulation in natural environment

This paper presents a generalized framework for the simulation of multiple robots and drones in highly realistic models of natural environments. The proposed simulation architecture uses the Unreal Engine4 for generating both optical and depth sensor outputs from any position and orientation...

Performance analysis of corner detection algorithms based on edge detectors

Detecting corner locations in images plays a significant role in several computer vision applications. Among the different approaches to corner detection, contour-based techniques are specifically interesting as they rely on edges detected from an image, and for such corner detectors, edge d...

Flexible moment invariant bases for 2D scalar and vector fields

Complex moments have been successfully applied to pattern detection tasks in two-dimensional real, complex, and vector valued functions. In this paper, we review the different bases of rotational moment invariants based on the generator approach with complex monomials. We analyze their prope...

Increasing diversity and usability of crowd animation systems

Crowd systems are a vital part in virtual environment applications that are used in entertainment, education, training or different simulation systems such as evacuation planning. Because performance and scalability are key factors, the implementation of crowds poses many challenges in many ...

Image-based information visualization: (or how to unify SciVis and InfoVis)

For decades, scientific visualization (SciVis) and information visualization (InfoVis) have been related, but still distinctly separated disciplines. Methods and techniques in the two areas have developed relatively separately, causing an arguably unnecessarily separation in the visualization field. Attempts&#x...
