Quarter Laplacian Filter For Edge Aware Image Processing

This paper presents a quarter Laplacian filter that can preserve corners and edges during image smoothing. Its support region is 2\times 2, which is smaller than the 3\times 3 support region of the classical Laplacian filter. Thus, it is more local. Moreover, this filter can be implemented via the c...
