Overview

This supplementary material illustrates equal-time comparisons between recent Monte Carlo (MC) image denoising methods and their corrected results using our method.

We test three denoising methods as our correlated images: KPCN [Bako et al. 2017], AMCD [Xu et al. 2019] and AFGSA [Yu et al. 2021].

We also compare deep combiner (DC) [Back et al. 2020] using retrained models with the results corrected by our approach given a same running time.

In the tables, we provide the total running time, samples per pixel (spp) and numerical accuracy (relative L2 [Rousselle et al. 2011] with small value 1e-2) for each result.
