Abstract: A computer-implemented method of processing a video stream comprises: feeding the at least one video stream to at least two video processing detectors, each comprising a respective deep convolutional neural network trained to detect one or more of the object or a property of the object; for each of said at least two video processing detectors, receiving a respective stream of object lightweight data records from the respective video processing detector, the stream of object lightweight data records generated based on the respective detection, and representing a property of the object; and feeding at least one stream of object lightweight data records to at least one context detector configured to perform a secondary detection based on object lightweight data of the stream of object lightweight data records, wherein the detections of the at least two video processing detectors are scheduled by a task-graph scheduler.

Abstract: A queue management system comprises a plurality of dynamic pedestrian barriers, each comprising a plurality of movable barrier arms carried by a barrier post, the plurality of dynamic pedestrian barriers being arranged in a two-dimensional grid pattern over a queuing area; and a controller configured to control the movable barrier arms of the dynamic pedestrian barriers to be reconfigurable between at least a first configuration, in which the plurality of dynamic pedestrian barriers define a first queue path between a queue entry and a queue exit, and a second configuration, in which the plurality of dynamic pedestrian barriers define a second queue path between the queue entry and the queue exit, the second queue path having a different path length.
