    摘要: Training a neural network to extract a degradation map from a degraded image comprises generating training data comprising pairs of images, each pair of images comprising a clean source image and a degraded source image by, for each clean source image, generating a corresponding noisy image by adding spatially invariant noise to the clean source image, and blending the noisy image with the clean source image according to varying intensity levels defined by a spatially variant mask to obtain the degraded image. The training data is used to train the neural network by inputting each degraded source image to the neural network and extracting a degradation map from the degraded source image such that when the degradation map is applied to its corresponding clean source image the loss between the degraded source image and its corresponding clean source image after the degradation map is applied is minimised.

    摘要: A video management system (VMS) including a recording server configured for receiving and storing a plurality of data streams and respective metadata streams, each data stream being supplied by, or associated with, respective ones of a plurality of streaming devices;



    a processing unit configured to receive data via a data communication interface, and further configured to:
    responsive to a trigger event, select a streaming device of the plurality of streaming devices, where the selected streaming device is associated with the trigger event,
    obtain position data associated with the selected streaming device, and
    determine a textual position description based on the position data of the selected streaming device at a time associated with the trigger event, wherein the textual position description describing a geographical position in a natural human language form with a common language syntax,
    wherein the VMS is configured to provide the textual position description.

    摘要: A method for setting parameters values of a video source device comprising obtaining a value of an image characteristic for a current image generated by the video source device set with initial parameters values; determining a satisfaction level for the image characteristic of the current image based on the obtained value, the satisfaction level representing a probability to fulfil a task; obtaining a set of candidates, a candidate being defined as a set of parameters values; for each candidate, predicting an evolution of the satisfaction level for the image characteristic relatively to the satisfaction level determined while the video source device is set with the initial parameters values; selecting a candidate based on its predicted evolution of the satisfaction level; setting the parameters values of the video source device using the set of parameters values of the selected candidate.
