PolSAR_GWLS_filter

This is a Matlab implementation demo of PolSAR GWLS filter.
In this demo, some operations are added to avoid computing exceptions, and the efficiency of the code is also improved.

Please refer to the following paper for a more detailed description of the algorithm.

1.The AutoParaforWLS2.m is used to determine parameters automatically.
2.The spanWLSfilterV2.m is used to do the global weighted least squares fitting.
3.The fPolRGBshow.m is used to visualize PolSAR images and it is helpful to visualize high resolution PolSAR images. We have used this code in the following paper for the high resolution PolSAR image visualization.
