     - ```temporal_filter``` - filter the depth image temporally.
     - ```hole_filling_filter``` - apply hole-filling filter.
     - ```decimation_filter``` - reduces depth scene complexity.
+    - ```rotation_filter``` - rotates depth and ir frames.

 Each of the above filters have it's own parameters, following the naming convention of `<filter_name>.<parameter_name>` including a `<filter_name>.enable` parameter to enable/disable it.
