Video to Event Simulator

This Python script allows you to transform frame-based image or video into event-based counterpart.

The source code of this script can be found in <install-prefix>/share/metavision/sdk/core_ml/python_samples/viz_video_to_event_simulator when installing Metavision SDK from installer or packages. For other deployment methods, check the page Path of Samples.

Expected Output

When launched on a video with default options, the script shows two windows with:

  • the original video

  • the corresponding event-based video produced by the simulator

When used with the -o option, a DAT file containing the simulated events is generated.

Setup & requirements

To run the script, you need:

  • a full path to the image file (in png or jpg format) or video (in mp4 or avi format).
