Light Field Denoising Using 4D Anisotropic Diffusion
ICASSP 2019accepted
In this paper, we present a novel light field denoising algorithm using a vector-valued regularization operating in the 4D ray space. More precisely, the method performs a PDE-based anisotropic diffusion along directions defined by local structures in the 4D ray space. It does not require prior esti…
