PolSAR Image Classification via D-KSVD and NSCT-Domain Features Extraction.

Polarimetric synthetic aperture radar (PolSAR) image classification is a powerful and important application in remote sensing. In this letter, we propose a PolSAR image classification method based on discriminative dictionary learning (D-KSVD) model and nonsubsampled contourlet transform (NSCT)-domain features. The D-KSVD model is used in our experiment to classify PolSAR images and is more time e...
