Multiscale Region-Level VHR Image Change Detection via Sparse Change Descriptor and Robust Discriminative Dictionary Learning

Figure 4

DS1 and the resultant change maps (CMs) by different methods. In the ground truth (GT) images and the CMs, the red regions denote the changed class and the other regions denote the unchanged class. In the training mask (TM) images, the red regions denote the changed class, the blue regions denote the unchanged class, and the remaining regions are unlabeled.
