Abstract :
A new sub-pixel target detection algorithm is developed, integrating the powerful "RX" anomaly detector of Reed and Yu (1990), with segmentation and post-processing filters. The integrated method consistently outperforms spectral anomaly detectors based on RX alone. A novel approach is presented to deal with false alarms caused by edges.
