Analysis of spatiotemporal signals: A method based on perturbation theory

摘要

We present a method of analyzing spatiotemporal signals with respect to its underlying dynamics. The algorithm aims at the determination of spatial modes and a criterion for the number of interacting modes. Simultaneously, a way of filtering of nonorthogonal noise is shown. The method is discussed by examples of simulated stable fixpoints and the Lorenz attractor. [S1063-651X(99)01908-X]. [References: 14]
