Light Field Denoising by Sparse 5D Transform Domain Collaborative Filtering

Light Field Denoising by Sparse 5D Transform Domain Collaborative Filtering

In this paper, we propose to extend the state-of-the-art BM3D image denoising filter to light fields, and we denote our method LFBM5D. We take full advantage of the 4D nature ...

Light Field Super-Resolution via LFBM5D Sparse Coding

Light Field Super-Resolution via LFBM5D Sparse Coding

In this paper, we propose a spatial super-resolution method for light fields, which combines the SR-BM3D single image super-resolution filter and the recently introduced LFBM5D light field denoising filter. The ...
