Abstract

Abstract:

It is difficult for many current despeckling methods to produce good region smoothing and edge preservation simultaneously. In this paper, a new Plural Pervasion equation is designed, which combines a Shearlet transform and edge detection of module maximum, and a new SAR image despeckling method is proposed. Experimental results indicate that the method possesses advantages of speckle reduction, and point target and edge preservation.

Key words: SAR image despeckling, Shearlet transform, plural pervasion, edge detection
