Decorrelating ReSTIR Samplers via MCMC Mutations
Rohan Sawhney, Daqi Lin, Markus Kettunen +4
Monte Carlo rendering algorithms often utilize correlations between pixels to improve efficiency and enhance image quality. For real-time applications in particular, repeated reser…
An unbiased ray-marching transmittance estimator
Markus Kettunen, Eugene d'Eon, Jacopo Pantaleoni +1
We present an in-depth analysis of the sources of variance in state-of-the-art unbiased volumetric transmittance estimators, and propose several new methods for improving their eff…
E-LPIPS: Robust Perceptual Image Similarity via Random Transformation Ensembles
Markus Kettunen, Erik Härkönen, Jaakko Lehtinen
It has been recently shown that the hidden variables of convolutional neural networks make for an efficient perceptual similarity metric that accurately predicts human judgment on…
