I am using ar_kinect and I'm getting some noise in the orientation. Since my camera motion is relatively slow I wanted to filter the transforms over time. I have designed an FIR filter. I was wondering what is the best way of filtering the transformations.

I was not sure if filtering quaternions would make any sense. Should I convert to RPY and apply the filter?

You should filter on the quaternions. Their main value is that they don't have singularities and can be cleanly interpolated, which are important if you want to filter.
