Demo for the proposed SSAL-SDP method, i.e., superpixel-based semisupervised active learning (SSAL) method with the density peak (DP) augmentation, for the hyperspectral image classification.

This set of files contains the Matlab code for the superpixel based semisupervised active learning (SSAL) with the density peak (DP) augmentation proposed in the following paper:
