Study on Denoising and Enhancement Method in SAR Image based on Wavelet Packet and Fuzzy Set

Abstract

Aiming at problem of denoising and enhancement in Synthetic Apertnre Radar (SAR) image, this paper proposes a fnsion of wavelet packet transform and fnzzy set algorithm for freqnency domain and fnzzy domain collaborative and joint processing to improve denoising and enhancement effect in SAR image. Firstly, wavelet packet transform was nsed to decompose SAR image in freqnency domain, and noise was removed by threshold qnantization. Then, the low freqnency part of SAR image was linearly transformed to enhance freqnency domain of SAR image. Finally, fnzzy set algorithm was nsed to enhance fnzzy domain of SAR image. In snmmary, this paper comprehensively proposes a SAR image denoising and enhancement algorithm combining wavelet packet and fnzzy set. The effectiveness and snperiority of proposed method are verified by experiments.
