Geometric filter for speckle reduction

Not Accessible

Your library or personal account may give you access

Abstract

An algorithm is described which reduces speckle noise in images. It is a nonlinear algorithm based on geometric concepts. Tests were performed on synthetic aperture radar images which show that it compares favorably with a 3 × 3 median filter.
