    - ```disparity``` - convert depth to disparity before applying other filters and back.
    - ```spatial``` - filter the depth image spatially.
    - ```temporal``` - filter the depth image temporally.
+   - ```hole_filling``` - apply hole-filling filter.
    - ```decimation``` - reduces depth scene complexity.
 - **enable_sync**: gathers closest frames of different sensors, infra red, color and depth, to be sent with the same timetag. This happens automatically when such filters as pointcloud are enabled.
 - ***<stream_type>*_width**, ***<stream_type>*_height**, ***<stream_type>*_fps**: <stream_type> can be any of *infra, color, fisheye, depth, gyro, accel, pose*. Sets the required format of the device. If the specified combination of parameters is not available by the device, the stream will not be published. Setting a value to 0, will choose the first format in the inner list. (i.e. consistent between runs but not defined). Note: for gyro accel and pose, only _fps option is meaningful.
