Abstract

This paper describes a new RXDMTD algorithm based on RX anomaly detection for moving weak and small targets in multispectral image sequences. The proposed algorithm can effectively suppress background clutter and at the same time enhance the moving weak and small targets in multispectral and out-of-time image sequences. The complex background intensity between the two multispectral images changes significantly, which makes it difficult to suppress the background and difficult to extract the target. In this paper, the image sequence is first arranged and combined, and then the RX algorithm is used to enhance the target and using the target’s movement suppresses the background. Experimental results show that the algorithm proposed in this paper has achieved good detection results.
