A new patch based change detector for polarimetric SAR data

作者：

Highlights：

• A new ENL estimator is proposed for the PolSAR/SAR data filtered by NLM filter.

• The distribution of the residual speckle in the filtered data is utilized.

• The proposed method is more efficient than the existing PolSAR change detectors.
