  Hi Nguyenduyduc14. The RealSense Viewer tool applies a range of post-processing filters by default, whilst scripts that you create yourself do not and have to have post-processing filters deliberately programmed into the script.  So if you are creating your own script, it will not have any post-processing filters applied by default.

   

  Intel provide a RealSense post-processing filter tutorial for Python at the link below.

  Also, this link is a useful reference:

  Thank MartyG,

  I read PyRealSense2. Should I program individual filter functions like the above example or use processing_block?

  I do not find an example that uses processing_block. Do you have some examples about processing_block?

  Hi,

  In postprocessing of the IntelRealSenseViewer, there is the HDR merge option. But I do not find it in filters functions of PyRealSense2.

  Do you have an example about the HDR merge option?

  Thanks

  Intel's white-paper guide about HDR has Python code for controlling HDR Merge at the link below.
