Re: Low pass filter on quaternions

I don't have any code handy, but since for a lowpass filter you need the "difference",  I guess you can obtain that with the inverse or something similar.. Also keep in mind it may be easier to just lowpass a 3x3 matrix since you want to rule out high freq noise

Hi,

I have a sequence of quaternions and want to filter out any high
frequency changes. I'm wondering if anyone has a paper or some code
for performing a low pass filter on quaternions?

Thanks,
