TRIGGER-RESPONSIVE CLIP EXTRACTION BASED ON REMOTE ANALYSIS

Abstract:

Intelligent Video Analytics system may be implemented using a distributed computing architecture with edge and remote devices, where the edge devices analyze the video stream and transmit detection data corresponding to time segments to the remote device. The detection data may identify an object (e.g., vehicle, pedestrian, etc.) in the video stream. The remote device analyzes the detection data received from one or more edge devices and generates extraction triggers that are transmitted to the one or more edge devices. When an edge device receives an extraction trigger, the edge device extracts a clip from the video stream and stores the clip to persistent storage. The remote device may then retrieve the clip. The edge devices may perform simple identification operations while the remote device implements complex algorithms to detect events, benefitting from a larger context than is available to the individual edge devices.
