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.

A Reconfigurable Camera Add-On for High Dynamic Range, Multispectral, Polarization, and Light-Field Imaging
SIGGRAPH 2013
Abstract
We propose a non-permanent add-on that enables plenoptic
imaging with standard cameras which we refer to as
KaleidoCamera. Our design is based on a physical copying
mechanism that multiplies a sensor image into a number of
identical copies that still carry the plenoptic information
of interest. Via different optical filters, we can then
recover the desired information. A minor modification of the
design also allows for aperture subsampling and, hence,
light-field imaging. As the filters in our design are
exchangeable, a reconfiguration for different imaging
purposes is possible. We show in a prototype setup that high
dynamic range, multispectral, polarization, and light-field
imaging can be achieved with our design.
