How to generate 'clean' event?

[Judenause]

I am attempting to generate clean-event data using v2e.
However, I have encountered an issue where the results do not appear to be clean data, regardless of whether I utilize dvs-params: clean or simply omit noise parameters altogether. I would greatly appreciate your guidance regarding what I might be doing incorrectly in my testing approach.

The command I have been using is as follows:

python v2e.py -i ../hotel-bar/pendulum.avi --overwrite --auto_timestamp_resolution=True --output_folder=/pendulum --dvs_aedat2 pendulum_clean.aedat --output_width=346 --output_height=260 --disable_slomo --dvs_text pendulum.txt --no_preview --dvs_params clean

python v2e.py -i ../hotel-bar/hotel-bar-aps.avi --overwrite --auto_timestamp_resolution=True --output_folder=/hotel-bar --dvs_aedat2 hotel-bar_clean.aedat --output_width=346 --output_height=260 --disable_slomo --dvs_text hotel-bar.txt --no_preview --dvs_params clean

the .aedat and .avi is here:

Thank you.

Thanks for asking.

The hotel-bar avi you are using is the OUTPUT of v2e. The hotel-bar data is a real recording that was denoised to provide a clean baseline of a sparse scene for DND21 benchmarking. It does not make sense to generate events from the v2e output DVS frames.

For the pendulum, you need to enable super-slomo, or the events will be basically quantized in time to the source frame times.
