Ray casting of multiple volumetric datasets with polyhedral boundaries on manycore GPUs
Found in: ACM Transactions on Graphics (TOG)
By Alexander Bornik, Bernhard Kainz, Dieter Schmalstieg, Judith Muehl, Markus Grabner, Stefan Hauswiesner, Alexander Bornik, Bernhard Kainz, Dieter Schmalstieg, Judith Muehl, Markus Grabner, Stefan Hauswiesner
Issue Date:December 2009
pp. 1-2
We present a new GPU-based rendering system for ray casting of multiple volumes. Our approach supports a large number of volumes, complex translucent and concave polyhedral objects as well as CSG intersections of volumes and geometry in any combination. Th...
     
Memory Efficient 3D Integral Volumes
Found in: 2013 IEEE International Conference on Computer Vision Workshops (ICCVW)
By Martin Urschler,Alexander Bornik,Michael Donoser
Issue Date:December 2013
pp. 722-729
Integral image data structures are very useful in computer vision applications that involve machine learning approaches based on ensembles of weak learners. The weak learners often are simply several regional sums of intensities subtracted from each other....
 
Liver Surgery Planning Using Virtual Reality
Found in: IEEE Computer Graphics and Applications
By Bernhard Reitinger, Alexander Bornik, Reinhard Beichel, Dieter Schmalstieg
Issue Date:November 2006
pp. 36-47
In liver surgery planning, 2D and desktop-based 3D systems offer surgeons limited assistance. By using VR technology to liberate 3D from 2D input devices such as the mouse and keyboard, this surgery planning system better supports surgeons. User studies sh...
 
Spatial Analysis Tools for Virtual Reality-based Surgical Planning
Found in: 3D User Interfaces
By Bernhard Reitinger, Dieter Schmalstieg, Alexander Bornik, Reinhard Beichel
Issue Date:March 2006
pp. 37-44
This paper presents a set of Virtual Reality-based interaction techniques for spatial analysis of medical datasets. Computer-aided medical planning tools often require precise and intuitive interaction for the quantitative inspection and analysis of anatom...
 
A Hybrid User Interface for Manipulation of Volumetric Medical Data
Found in: 3D User Interfaces
By Alexander Bornik, Reinhard Beichel, Ernst Kruijff, Bernhard Reitinger, Dieter Schmalstieg
Issue Date:March 2006
pp. 29-36
This paper presents a novel system for interactive visualization and manipulation of medical datasets for surgery planning based on a hybrid VR / Tablet PC user interface. The goal of the system is to facilitate efficient visual inspection and correction o...
 
Multiresolution Texture for Photorealistic Rendering
Found in: Computer Graphics, Spring Conference on
By Heinz Mayer, Franz Leberl, Alexander Bornik, Joachim Bauer, Konrad Karner
Issue Date:April 2001
pp. 0109
Abstract: This paper presents a method to automatically calculate texture maps for a given 3-dimensional object out of a sequence of images. It is used in our image-based modeling approach after the registration of the images and the geometric modeling is ...
 
Forensic-Case Analysis: From 3D Imaging to Interactive Visualization
Found in: IEEE Computer Graphics and Applications
By Martin Urschler,Alexander Bornik,Eva Scheurer,Kathrin Yen,Horst Bischof,Dieter Schmalstieg
Issue Date:July 2012
pp. 79-87
An interactive framework prepares raw computed-tomography and magnetic-resonance-imaging scans for courtroom presentations. The framework makes use of combined computer graphics and computer vision techniques to enable a forensic case analysis workflow.

Interactive editing of segmented volumetric datasets in a hybrid 2D/3D virtual environment
Found in: Proceedings of the ACM symposium on Virtual reality software and technology (VRST '06)
By Alexander Bornik, Dieter Schmalstieg, Reinhard Beichel
Issue Date:November 2006
pp. 197-206
In this paper we present a novel system for segmentation refine-ment, which allows for interactive correction of surface models generated from imperfect automatic segmentations of arbitrary volumetric data. The proposed approach is based on a deformable su...
