In this section, we propose an unsupervised superpixel-level compressed change vector analysis (SPC²VA) approach for multiclass CD. The traditional pixel-level spectral change analysis is converted into the superpixel level. Therefore, the spectral change representation and identification are regularized and enhanced under the superpixel constraints. The block scheme of the proposed approach is shown in Figure 1.4.
