Generalized Image Acquisition and Analysis
Performance Capture of High-Speed Motion Using Staggered Multi-View Recording
We present a markerless performance capture system that can acquire the motion and the texture of human actors
performing fast movements using only commodity hardware. To this end we introduce two novel concepts: First, a
staggered surround multi-view recording setup that enables us to perform model-based motion capture on motion-blurred
images, and second, a model-based deblurring algorithm which is able to handle disocclusion, self-occlusion and
complex object motions. We show that the model-based approach is not only a powerful strategy for tracking but also for
deblurring highly complex blur patterns.

Volume Stylizer: Tomography-based Volume Painting
I3D 2013
Abstract
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.
