Anomaly Detection Technique of HSI

Due to the significant value in both military area and civil area, hyperspectral remote sensing imagery detection has been widely developed in recent 20 years. Anomaly detection algorithms could detect pixels, which is distinct from the surrounding background without any prior knowledge. In real applications, anomaly detection has received considerable interest in hyperspectral imaging since it is very difficult to obtain target information, and on the other hand, it is influenced by atmospheric transport, background, and imaging equipment error.
