Hyperspectral collaborative sparse unmixing based on fusion of stacked edge-preserving filterings

The spatial resolution of the hyperspectral image is usually low, the endmembers are uniformly mixed, and a single pixel usually contains multiple mixed endmembers. In order to extract a single endmember and its corresponding abundance coefficient in the hyperspectral images, a hyperspectral linear collaborative sparse unmixing method based on edge-preserving filtering is proposed. Firstly, the mu...
