Ali Jamali, Swalpa Kumar Roy, Avik Bhattacharya, and Pedram Ghamisi

This Keras code is for the paper A. Jamali, S. K. Roy, A. Bhattacharya and P. Ghamisi, "Local Window Attention Transformer for Polarimetric SAR Image Classification," in IEEE Geoscience and Remote Sensing Letters, doi: 10.1109/LGRS.2023.3239263 [https://ieeexplore.ieee.org/document/10024822].

Dataset

Flevoland dataset: NASA/JPL AIRSAR recorded the data of Flevoland, situated in the Netherlands, on August 16, 1989. The Flevoland image is $750\times1024$ pixels in size.

San Francisco dataset: The San Francisco illustrates a NASA/JPL AIRSAR L-band image of the San Francisco area. The resolution of the data of the San Francisco is $900\times1024$ pixels.
