Overview

In this supplemental material, we compare our technique to state-of-the-art denoisers (KPCN [1] and AFGSA [2]) and post-denoisers (DC [3], ED [4] and PD [5]). In addition, our method is compared with BDPT [6] and SPPM [7]. The full-resolution results of the tested techniques correspond to the results in the main paper.
