Paper on accelerating path tracing using eye path reprojection available

The paper "Accelerating path tracing by eye path reprojection" by Niklas Henrich et al., which I blogged about earlier is available from http://www.rendering.ovgu.de/publikationen.html. The algorithm achieves similar quality as regular path tracing in half the time and can easily be ported to the GPU. The authors also plan to incorporate their technique into a real-time raytracer.
