What is Weighted Guided Image Filtering Enhanced about?

This document summarizes a research article that proposes a novel weighted guided image filter (WGIF) using a steering kernel. Guided image filtering suffers from halo artifacts near edges due to its local property. Existing WGIF incorporates edge-aware weighting but does not fully consider edge direction. The proposed method leverages edge direction more by using a steering kernel to adaptively learn direction and incorporate it into filtering. Theoretical analysis and experiments show it preserves edges a
