Abstract:
Smoothing and sharpening are two fundamental operations in image processing, and they are usually conducted separately. In this
paper, an improved weighted guided image filter (iWGIF) is first
proposed to enhance existing guided filters. A content adaptive
smoothing and sharpening (CASS) algorithm is then presented by
using coefficients of the iWGIF intelligently. A simple despeckling algorithm is finally introduced to simultaneously smoothen
homogeneous regions and preserve heterogeneous regions of syntheticaperture radar images. Experimental results validate all the proposed algorithms.
