Abstract: A method for generating and providing artificial intelligence assisted surgical guidance includes analyzing video images from surgical procedure and training a neural network to identify at least one of anatomical objects, surgical objects, and tissue manipulation in video images. The method includes receiving, by the neural network, a live feed of video images from the surgery. The method further includes classifying, by the neural network, at least one of anatomical objects, surgical objects, and tissue manipulation in the live feed of video images. The method further includes outputting, in real time, surgical guidance based on algorithms created using the classified at least on of anatomical objects, surgical objects, and tissue manipulations in the live feed of video images.

Abstract: The invention relates to methods and apparatuses for managing storage and serving of data streams generated by peripheral devices in a system for surveillance and/or monitoring. According to one aspect, the method comprises the steps of obtaining a configuration table, the configuration table comprising a list of one or more recording servers storing data segments generated by the peripheral device; building an association table, the association table comprising, for each recording server of the list, identifiers of data segments of the data stream stored therein; determining, based on the association table, the recording server storing a requested data segment; obtaining the requested data segment from the determined recording server and serving the obtained data segment.

Abstract: A method of acquiring a training set of images is carried out in an environment comprising at least one video surveillance camera, wherein the video camera is connected to a network including a video management server. The method comprises controlling a robot having an object attached to navigate to a plurality of locations, wherein each location is in the field of view of at least one camera. At each location, at least one camera which has the robot in its field of view is controlled to capture a plurality of images with different camera settings. Each image is stored with camera setting data defining the camera settings when the image was captured.

Abstract: A current motion grid comprising a plurality of elements is generated by storing in each element of the current motion grid an indication of whether there is a change between corresponding elements of at least two images captured from a video sequence. A current motion pattern grid comprising a plurality of elements is generated by firstly searching for a segment consisting of grid elements in which a change has been indicated in the current motion grid and which are neighbouring to one another and, secondly, storing in each element of the segment a value corresponding to a size of the segment. A value of an element of the current motion pattern grid is compared with a threshold value. It is then determined, based on the result of the comparison, whether there is deviation from the motion pattern.

Abstract: Detection of motion deviation in a video sequence is provided. Change grids each comprise elements generated by storing in each element of the change grid an indication of whether there is change between corresponding elements of at least two images. A current direction grid is generated from a pair of change grids by searching for movement of a corresponding segment identified in each change grid, the movement occurring between the locations of the segment in each of the pair of change grids and, storing in elements of the current direction grid a vector corresponding to the movement of the segment. A vector stored in an element of the current direction grid is compared with a reference vector. It is determined whether there is motion deviation in the video sequence in accordance with the comparison.
