Hyperspectral Anomaly Detection via Integration of Feature Extraction and Background Purification
IEEE Geoscience and Remote Sensing Letters(2021)
摘要
Anomaly detection (AD) has become a hotspot in hyperspectral imagery (HSI) processing due to its advantage in detecting potential targets without prior knowledge, and a variety of algorithms are proposed for a better performance. However, they usually either fail to extract intrinsic features underlying HSIs, or suffer from the contamination of noise and anomalies. To address these problems, we pr...
