Abstract: A method for improving settings of a camera, the method comprising: obtaining a first set of setting parameters that are adjustable by an auto-setting algorithm, the setting parameters of the first set being set as a function of a task to be performed based on images obtained from the camera; obtaining a second set of setting parameters, the setting parameters of the second set being setting parameters of the camera, values of which are settable remotely from the camera; determining, as a function of the first and second sets of setting parameters, whether the auto-setting algorithm and the camera are compatible to perform the task; and if the auto-setting algorithm and the camera are compatible to perform the task, executing the auto-setting algorithm to adjust values of setting parameters of the camera.

Abstract: A computer implemented method of anonymising video surveillance data of a scene and detecting an object or event of interest in such anonymised video surveillance data, the method comprising segmenting frames of video surveillance data of at least one scene into corresponding frames of segmented data using image segmentation, wherein a mask label is assigned to every pixel of each frame of the segmented data based either on a class of objects or of surfaces or on an instance of such a class that pixel belongs to, and detecting at least one object and/or event of interest based on at least one shape and/or motion in at least one frame of the segmented data.

Abstract: A method for setting a parameter value of a first video source device comprises:
determining a first set of image characteristic values from an image captured by the first video source device configured with a first set of parameter values;
obtaining a second set of image characteristic values generated from an image captured by a second video source device different from the first video source device, the second video source device being configured with a second set of parameter values;
determining if the obtained second set of image characteristic values comprises values equivalent to values of the determined first set of image characteristic values; and if there are equivalent values, setting the parameter value of the first video source device using the second set of image characteristic values.

Abstract: A method of obtaining an attention matrix for use in a transformer-based model, a non-transitory computer readable storage medium, and an apparatus are provided. The method includes applying an attentional mechanism over a quadtree representation of an input image. The method may be used for image classification, for example in the field of video surveillance.

Abstract: A video surveillance system comprising an operator client including a system memory, a plurality of display devices for displaying video data and resources for decoding of encoded video data for display, including a plurality of GPUs, wherein each of the display devices is connected to a graphics output port of one of the GPUs. A load distribution module is configured to send a stream of encoded video data to one of the decoding resources by determining a first display device the stream of video data is to be displayed after decoding, and sending the stream of video data to a first GPU for decoding and display on the selected display device, wherein the first GPU is connected to the first display device, unless the first GPU is overloaded. If the first GPU is overloaded, the load distribution module sends the stream of video data to a second GPU for decoding.

Abstract: A computer-implemented method of video surveillance comprising the steps of: querying a knowledge graph representing a plurality of video cameras as ontology entities connected by edges, in order to identify, based on a first video camera providing a first video stream that can be fed to at least one first application program to obtain first analytics data, one or more second video cameras which can each provide a respective second video stream; and identifying, based on the first application program and/or based on the first analytics data, at least one second application program that can be fed with at least one second video stream to obtain second analytics data.

Abstract: A method of training a machine learning algorithm to identify objects or activities in video surveillance data comprises generating a 3D simulation of a real environment from video surveillance data captured by at least one video surveillance camera installed in the real environment. Objects or activities are synthesized within the simulated 3D environment and the synthesized objects or activities within the simulated 3D environment are used as training data to train the machine learning algorithm to identify objects or activities, wherein the synthesized objects or activities within the simulated 3D environment used as training data are all viewed from the same viewpoint in the simulated 3D environment.

Abstract: A computer-implemented method of generating a video stream recommendation comprises identifying a plurality of peripheral devices monitoring zones of a physical area, the peripheral devices comprising a plurality of video cameras providing video streams of at least some of the monitored zones. The method further comprises querying a knowledge graph representing the peripheral devices and the monitored zones as ontology entities connected by edges representing physical paths between the monitored zones, and by edges representing which monitored zones the peripheral devices monitor, in order to identify a set of one or more video camera(s) monitoring zones other than a selected monitored zone, as a result of the querying. The method then comprises generating a video stream recommendation based on the result of the querying.
