ReBLUR: A Hierarchical Recurrent Denoiser
Dmitry Zhdan · Apress eBooks · 2021
This chapter presents ReBLUR: a hierarchical recurrent denoiser, currently deployed in recent RTX game titles, including Cyberpunk 2077 and Watch Dogs: Legion. By aggressively reusing information both spatially and temporally, the denoiser produces noise-free images from only a few samples per pixel. In this chapter, we describe the internal structure of the denoiser in detail, and we hope that the basic blocks of this architecture can be useful to improve future denoisers.
