Title:
SYSTEMS AND METHODS FOR VIDEO ANALYSIS
Document Type and Number:
WIPO Patent Application WO/2022/012002
Kind Code:
A1
Abstract:
The present disclosure relates to systems and methods for video analysis. The systems may obtain a plurality of video data streams to be analyzed. A count of the plurality of video data streams may exceed a computing power of at least one processor of the system. The computing power may indicate a count of video data streams that the at least one processor can handle simultaneously. For each of the plurality of video data streams, the system may extract at least one frame from the video data stream based on a predetermined time interval. The systems may identify, using a portion of the computing power, one or more target video data streams each of which is associated with a preset target object from the plurality of video data streams based on the extracted frames. The systems may analyze, using at least part of remainder portions of the computing power, the one or more target video data streams.
