Generalized Image Acquisition and Analysis
Volume Stylizer: Tomography-based Volume Painting
Volumetric phenomena are an integral part of standard
rendering, yet, no suitable tools to edit characteristic
properties are available so far. Either simulation results
are used directly, or modifications are high-level, e.g.,
noise functions to influence appearance. Intuitive artistic
control is not possible.
We propose a solution to stylize single-scattering
volumetric effects. Emission, scattering and extinction
become amenable to artistic control while preserving a
smooth and coherent appearance when changing the
viewpoint. Our approach lets the user define a number of
target views to be matched when observing the volume from
this perspective. Via an analysis of the volumetric
rendering equation, we can show how to link this problem to
tomographic reconstruction.

A Mathematical Model and Calibration Procedure for Galvanometric Laser Scanning Systems
In: Vision, Modeling, and Visualization (VMV 2011)
Abstract
Laser galvanometric scanning systems are commonly used in various fields such as three dimensional scanning,
medical imaging, material processing, measurement devices and laser display systems. The systems of such kind
suffer from distortions. On top of that they do not have a center of projection, which makes it impossible to use
common projector calibration procedures. The paper presents a novel mathematical model to predict the image
distortions caused by galvanometric mirror scanning systems. In addition, we describe a calibration procedure
for recovering its intrinsic and extrinsic parameters.
