Spatiotemporal wavelet transform: application to target detection and recognition
K. Bouyoucef, Romain Murenzi · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1995
The motion analysis of a time dependent signal in 1D of space and time using the spatio- temporal continuous wavelet transform [(1 + 1) CWT] allows signature detection of the moving objects. In this paper we first review some relevant properties of the (1 + 1)D CWT. We then apply it to motion analysis of some academic signals plunged in a cluttered medium. From there we infer a strategy for detection and recognition of moving targets. In the appendix we give analytical results of (1 + 1)D CWT applied to two basic signals: N ponctual moving objects, and N moving plane waves.
