This Python sample has a corresponding C++ sample.
Filtering using Python
metavision_filtering.py shows how to use the Python bindings of Metavision Core SDK to filter and display events.
It also shows how to capture the keys pressed in a display window and use them to modify the behavior of the stages
while the pipeline is running.
The following filters can be applied via keyboard keys:
metavision_sdk_core.PolarityFilterAlgorithmused to show only events of positive polarity
metavision_sdk_core.PolarityFilterAlgorithmused to show only events of negative polarity
The sample visualizes CD events from an event-based device or a RAW file after filtering:
How to start
To start the sample based on the live stream from your camera, run:
To start the sample based on recorded data, provide the full path to a RAW file (here, we use the file
from our Sample Recordings):
python3 metavision_filtering.py -i spinner.raw
python metavision_filtering.py -i spinner.raw
