Code for the paper: Multi-direction Networks with Attentional Spectral Prior for Hyperspectral Image Classification.

Fig. 1: The framework of our proposed MDN-ASP for HSI classification. It is composed of four components: multi-direction samples construction, multi-stream feature extraction, feature aggregation with attentional spectral prior (ASP) and a softmax-based classifier. The same color represents the layers with same operation.

Training and Test Process

Please firstly run the 'generate_train_val_test_gt.m' to generate the training and test maps. Then, run 'construct_multi_mat.py' to construct the multi-direction samples. Finally, run 'main_MDN_ASP.py' to reproduce the MDN-ASP results on IndianPines data set. The training samples distribution and the obtained classification map are shown below. We have successfully test it on Ubuntu 16.04 and Windows systems with Matlab R2017b. Part of the source code are employed from the works of DR-CNN and SSRN.
