Brawl Detection

Feature Description

Brawl detection is designed to identify fighting incidents in video streams, providing real-time information for police departments and offering data reference for emergency dispatch of police officers.

Feature Entry

  • Video Analysis tab -> Transport Analysis group -> Other Models drop-down button -> Brawl Detection.

Steps

  1. Click Video Analysis tab -> Transport Analysis group -> Other Models drop-down button -> Brawl Detection Settings;
  2. Parameter descriptions in the brawl detection settings dialog:
    • Sampling Frame Count: The cumulative number of sampled frames required to trigger fight recognition. For example, when set to 8, a fight will be recorded only if 8 consecutive sampled frames all indicate fighting activity.
    • Sampling Frequency: The interval between frame sampling. For example, a value of 6 means sampling every 6th frame.
    • Probability Threshold: Detection results will be displayed in video when probability exceeds this value. Default value is 0.9, valid range [0-1].
    • The Participate in a Brawl list displays all detection types from current Detection Settings. Ensure "Human" type is selected.
  3. Activate Brawl Detection. When fighting is detected, an alert will appear in the upper-left corner of the video window.
