Delayed Rejection Metropolis Light Transport
Evaluation
To showcase the benefits of our approach, we integrated our two-stage method into three algorithms: Primary Sample Space MLT (PSSMLT) [Kelemen et al. 2002], Multiplexed MLT (MMLT) [Hachisuka et al. 2014] and Hessian-Hamiltonian MLT (H2MC) [Li et al. 2015]. We report the L1, L2 and relative mean squared error (rMSE) of the average run for all scenes. We also include the acceptance map for our two-stage method.
