要旨:
Sophisticated video processing effects require both image and geometry
information. We explore the possibility to
augment a video camera with a recent infrared time-of-flight depth camera, to
capture high-resolution RGB and
low-resolution, noisy depth at video frame rates. To turn such a setup into a
practical RGBZ video camera, we
develop efficient data filtering techniques that are tailored to the noise
characteristics of IR depth cameras. We first
remove typical artefacts in the RGBZ data and then apply an efficient
spatiotemporal denoising and upsampling
scheme. This allows us to record temporally coherent RGBZ videos at interactive
frame rates and to use them
to render a variety of effects in unprecedented quality. We show effects such
as video relighting, geometry-based
abstraction and stylisation, background segmentation and rendering in
stereoscopic 3D.
