Abstract :
This article presents a way to build a Wiener filter for rotation processes using ordered exponential. Comparison is made with other approaches known to build up filters on Lie groups. Explicit reconstruction errors are given for the different possible filters. The advantages of using ordered exponential is illustrated on simulated rotation data.
