P ol SAR快速贝叶斯非局部均值相干斑抑制方法
Fast Bayesian non-local means of polarimetric SAR image despeckling
摘要
Abstract
Based on the Bayesian non-local means of the single polarization SAR,block similarity measurement of the polarimetric coherence matrix is derived by combining with the polarimetric coherence matrix adhering to complex Wishart distribution.The polarimetric SAR Bayesian non-local means model is given without prior knowledge.Then its fast algorithm is realized using the integral image.Finally,we verify the proposed algorithm with a full polarimetric image from AIRSAR to San Francisco district.Experimental results from real Polarimetric SAR data show that the proposed algorithm not only despeckes effectively but also preserves polarimetric information well.Besides,computing efficiency is improved greatly.关键词
