Application of the Extended Kalman Filter for Denoising Movies of the Dynamics of the Dielectric Polarization

Abstract

The extended Kalman filter has been generated to denoise movies of dynamical processes. In the first applications it has been used for systems with only a few degrees of freedom, for instance to denoise the movies of a flying rocket. Later it was suggested for a system with very many degrees if freedom, namely for denoising movies of the fast dissipative magnetization dynamics. The techniques used to produce such movies were the X-ray magnetic circular dichroism (XMCD). There the number N of degrees of freedom is extremely large, typically N
