1. A method for filtering an input image to generate a base layer and a detail layer, the method comprising:
applying a spatial filter to the input image to generate the base layer and the detail layer, the filtering comprising for each of a plurality of pixels:
detecting the presence of an edge of the input image within a region surrounding the pixel; and
selectively applying a filtering kernel to the region based on the presence of the edge within the region.
