A framework for wait-free data exchange in massively threaded VR systems

A central part of virtual reality systems and game engines is the generation, management and distribution of all relevant world states. In modern interactive graphic software systems usually many independent software components need to communicate and exchange data. Standard approaches...

Using metrics to evaluate and improve text-based information visualization in 3D urban environment

Information visualization is widely involved in our daily life. It develops rapidly in both 2D and 3D environments. In the 3D case, evaluation is a critical problem. Existent evaluation metrics are firstly introduced in this paper. We chose to focus on mathematical metrics&#...

Estimating the vanishing point of a sidewalk

In this paper, we propose an algorithm estimating the vanishing point (VP) of a sidewalk in a man-made environment from a single image. For finding the VP, the lines in an image are efficiently exploited as a clue because the projections of parallel lines in a...

Parallel iso-surface extraction and simplification

When extracting iso-surfaces from large volume data sets, long processing times are required and a high number of polygons is generated. We propose a massively parallel iso-surface extraction and simplification algorithm. The extraction is based on the marching cubes algorithm. In...

Multi scale color coding of derived curvature and torsion fields on a multi-block curvilinear grid

We present a method to compute and visualize the curvature and torsion scalar fields derived from a vector field defined on a multi-block curvilinear grid. In order to compute the curvature and torsion fields, we define a uniform Cartesian grid of points in the vol...

Histogram of structure tensors: application to pattern clustering

Pattern clustering is an important data analysis process useful in a wide spectrum of computer vision applications. In addition to choosing the appropriate clustering methods, particular attention should be paid to the choice of the features describing patterns in order to improv...

Personal health data: visualization modalities and their perceived values

In this paper we focus on universal human values as defined by Schwartz [Schw92] in the context of visualizing personal health data. Can data visualizations convey human values? We have explored various modalities of presenting health data and found that personal health visu...

User-based visual-interactive similarity definition for mixed data objects: concept and first implementation

The definition of similarity between data objects plays a key role in many analytical systems. The process of similarity definition comprises several challenges as three main problems occur: different stakeholders, mixed data, and changing requirements. Firstly, in many applications the&#x...

Reconstruction & interaction with 3D simplified bone models

Visualization and interaction with 3D bone models reconstructed from medical images are fundamental for biomedical applications. They are useful for surgeons in order to diagnose and plan surgical operations. Although traditional reconstruction techniques based on isosurfacing are mainly used&#...

Three-dimensional blood vessel modeling method considering IVUS catheter insertion

In this paper, we propose a new 3D (three-dimensional) blood vessel modeling method for FSI (fluid-structure interaction) analysis. Because of the nature of medical images, a 3D blood vessel model that includes intima and adventitia cannot be reconstructed using a single medical&...

Semi-automatic segmentation of prostate by directional search for edge boundaries

Semi-automatic segmentation of the prostate boundary is presented for the pre-operational images of the MRIguided ultrasonic thermal therapy of the prostate cancer. The specific deformable surface method is based on firstly fitting an ellipsoid on the given manual landmark points, the...

Physics-based modelling and animation of saccadic eye movement

In this paper we present a new approach in producing realistic saccade eye movement animations by incorporating anatomical details of the oculomotor system into the dynamics of the eye model. Unlike abstract models of the eye motor behaviour, we make use of a biomedical...

Pose estimation of small-articulated animals using multiple view images

The study of robots that mimic the behavior of small animals such as lizards and arthropods has been actively carried out. However, systematic analysis of the gait behavior of small animals is not prevalent in the literature. Motion analysis of most living creatures is&...

3D visualization of UCG process

The paper presents the aspects of 3D graphics utilization in the visualization of underground coal gasification (UCG) process. Data gathered during the process as well as achieved by the mathematical modelling describe a three dimensional structure of the georeactor where the pro...

SAMI: SAliency based metrics of Identification for object concealment evaluation

We propose original metrics for estimation of detection and identification of an object in an image. SAMI (SAliency based Metrics of Identification) gives a detection score, called D_score, and an identification score, called I_score, for a Region Of Interest (ROI), basically the...
