  • Publication number: 20230136403
    Abstract: A method and device for event displaying, a computer-readable storage medium, and an electronic device. The method comprises: acquiring parameter information of multiple users in a preset area (S110); determining, on the basis of parameter information, the probabilities of events to be displayed being triggered (S120); and determining, on the basis of the probabilities, a duration for displaying said events in the preset area (S130). The method overcomes the problem of data resource wastage in the prior art in which a greater number of invalid events are displayed when displaying events without taking into consideration parameter information of users.

  • Patent number: 11455735
    Abstract: The present disclosure relates to a target tracking method, device, system, and a non-transitory computer-readable storage medium. The method includes: determining an area where a current target is located by performing target detection on a current frame image; extracting a current position information of the area where the current target is located; predicting a position information of an area where each historical target is located at a corresponding moment of the current frame image based on historical position information of an area where each historical target is located in one or more historical frame images; determining a historical target that is the same target as the current target based on a position difference between the current position information and the predicted position information, and tracking the current target.
