Interactive Reconstruction of Monte Carlo Image Sequences using a Recurrent Denoising Autoencoder

Tensorflow Implementation and some visual results of SIGGRAPH'17 paper: Interactive Reconstruction of Monte Carlo Image Sequences using a Recurrent Denoising Autoencoder by Chakravarty R. Alla Chaitanya, Anton Kaplanyan, Christoph Schied, Marco Salvi, Aaron Lefohn, Derek Nowrouzezahrai and Timo Aila

Architecture

We use the same architecture proposed in the paper instead we change the recurrent block to ConvLSTM blocks.

Training

python main.py --dataPath /path/to/data --outputPath /path/to/output_folder 

Data Acquisition

We use pbrt-v3 to render 1 spp, 4096 spp, and auxiliary features as training pairs. Example input features in grey scale and reference in bathroom scene (a) 1 spp MC rendering with Halton sampler, (b) depth, (c) shading normal x-axis, (d) shading normal y-axis, (e) roughness, and (f) 4096 spp reference.
