Local Laplacian Filters: Edge-aware Image Processing with a Laplacian Pyramid

Local Laplacian Filters

In this paper, we demonstrate that state-of-the-art edge-aware filters can be achieved with standard Laplacian pyramids.

Technical Perspective: Image Processing Goes Back to Basics

In "Local Laplacian Filters," Paris et al. made a surprising move. They chose to build a system on the Laplacian pyramid, which is a very simple multiscale representation that predates wavelets.
