Abstract

The present disclosure relates to a system for action recognition in a video sequence. The system comprises a camera (100) configured to capture the video sequence and a server (200) configured to perform action recognition. The camera comprises an object identifier (124) configured to identify an object of interest in an object image frame of the video sequence; an action candidate recognizer (126) configured to apply a first action recognition algorithm to the object image frame and thereby detecting presence of an action candidate; an video extractor (127) configured to produce action image frames of an action video sequence by extracting video data pertaining to a plurality of image frames from the video sequence, wherein one or more of the plurality of image frames from which the video data is extracted comprises the object of interest; and a network interface (130) configured to transfer the action video sequence to the server. The server comprises an action verifier (210) configured to apply a second action recognition algorithm to the action video sequence and thereby verify or reject that the action candidate is an action. Also a method for action recognition in a video sequence is presented.
