DOI: 10.1109/access.2020.2999891

Abstract: A novel reconstruction algorithm is presented to address the noise artifacts of path tracing. SURE (Stein’s unbiased risk estimator) is adopted to estimate the noise level per pixel that guides adaptive sampling process. Modified MLPs… read more here.

DOI: 10.1111/cgf.14481

Abstract: Rendering photo‐realistic images using Monte Carlo path tracing often requires sampling a large number of paths to reach acceptable levels of noise. This is particularly the case when rendering participating media, that complexify light paths… read more here.

DOI: 10.48550/arxiv.2207.11586

Abstract: It is common to advise against using 3D to visualize abstract data such as networks, however Ware and Mitchell's 2008 study showed that path tracing in a network is less error prone in 3D than… read more here.
