Dear all,
VICON software (Workstation or Nexus) comes with a Woltring filtering routine, with predefined parameters (in the DynamicPluginGait pipeline of Nexus: of MSE=10). Unfortunately I could not find any information on the properties of the Woltring filter and on the effect of different MSE values. Who can help me with that?
On isbweb.org I found a rather vague statement on the equivalence of Woltring and Butterworth filtering (for certain kinds of data) - what is the relationship, in particular, is there a direct translation between the MSE-parameter for Woltring and the cut-off frequency for the Butterworth?
Do you have recommendations on choosing MSE for the Woltring filter - in this specific case for kinematic walking data sampled at 200 Hz?
Many thanks in advance, best wishes,
