JVET-AF0274 AHG13/AHG3: film grain tuning tool [P. de Lagrange (InterDigital)] [late]

This contribution describes a new tool to graphically display and edit an FGC SEI configuration file, available in the JVET gitlab (in “JVET AHG Film Grain Technologies” group).

A recent addition is “FGC SEI designer”, a graphical interactive tool to edit an FCG SEI config file, that can be useful when automatic estimation is either not practical or needs to be refined. It can also be used to export a graphical representation of film grain parameters, for use e.g. in a document.

As it is implemented as a single python script, and supposed to be connected to a film grain synthesizer, it was just added to the “VFGS” software repository (https://vcgit.hhi.fraunhofer.de/jvet-ahg-fgt/vfgs), rather than creating a new repository. External dependencies are matplotlib and numpy.

The tool is also available from the InterDigital github (https://github.com/InterDigitalInc/VersatileFilmGrain), which is in fact its primary source.

An impressive demonstration was given.
