(LaTeX) Abstract:

Currently 3D animation rendering and video compression are completely independent processes even if rendered
frames are streamed on-the-fly within a client-server platform. In such scenario, which may involve time-varying
transmission bandwidths and different display characteristics at the client side, dynamic adjustment of the rendering
quality to such requirements can lead to a better use of server resources. In this work, we present a framework where
the renderer and MPEG codec are coupled through a straightforward interface that provides precise motion vectors
from the rendering side to the codec and perceptual error thresholds for each pixel in the opposite direction. The
perceptual error thresholds take into account bandwidth-dependent quantization errors resulting from the lossy compression
as well as image content-dependent luminance and spatial contrast masking. The availability of the discrete
cosine transform (DCT) coefficients at the codec side enables to use advanced models of the human visual system
(HVS) in the perceptual error threshold derivation without incurring any significant cost. Those error thresholds
are then used to control the rendering quality and make it well aligned with the compressed stream quality. In our
prototype system we use the lightcuts technique developed by Walter et al., which we enhance to handle dynamic
image sequences, and an MPEG-2 implementation. Our results clearly demonstrate many advantages of coupling
the rendering with video compression in terms of faster rendering. Furthermore, temporally coherent rendering leads
to a reduction of temporal artifacts.
