Superpixel Spectral Unmixing for Hyperspectral Image Superresolution Using a Coupled Encoder-Decoder Network

Figure 1

The schematic diagram of the proposed approach: (1) cluster the high-resolution MSI into superpixels; (2) unmix the low-resolution HSI and superpixels in MSI to obtain endmember and abundance matrix with useful constrains by a coupled network.
