I was trying to find out the parameters which are used as standard in PCL's bilateral filtering routine for Kinect images.

As I understand it, the required parameters for bilateral filtering are:

  • Spatial Gaussian width
  • Gaussian width in the range dimension
  • Width in pixels over which the filter operates

Are these parameters hard coded into the Bilateral filtering routine? If so, where can I find them? If not, what parameters are typically used with Kinect images?

There are several bilateral filters in PCL:

  1. BilateralFilter, no defaults.
  2. FastBilateralFilter, default is 15.0f spatial width and 0.05f range sigma.
  3. Bilateral filter in KinFu, uses 4.5f spatial width and 0.03f range sigma.
