Self-Guided Filter with Multi-Scale Box Filter

Abstract

We present an edge-aware filter using multi-scale box filter (MSBF). In our method, multiple filtered results are adaptively weighted, which depend on image edge and gradient, and summed. The proposed filter achieves better result in 1)image enhancement and 2)image denoising application compared with guided filter, i.e. 1)avoiding luminance saturation, 2)preserving edges.
