Claim Text:
1. A video synopsis method, comprising: extracting at least two moving objects and moving tracks of the at least two moving objects from an original video; obtaining a spatio-temporal redundancy between the at least two moving tracks, and determining a synopsis ratio of the moving tracks according to the spatio-temporal redundancy; and synopsizing the moving tracks of the moving objects according to the synopsis ratio of the moving tracks; wherein the original video comprises at least one video segment, and before the obtaining the spatio-temporal redundancy between the at least two moving tracks, and determining the synopsis ratio of the moving tracks according to the spatio-temporal redundancy, the method further comprises: acquiring, from the at least one video segment, one or more time coordinate values corresponding to time points of start frames and end frames of the moving objects, and spatial coordinate values passed by the moving tracks of the moving objects; and the obtaining the spatio-temporal redundancy between the at least two moving tracks, and determining the synopsis ratio of the moving tracks according to the spatio-temporal redundancy further comprises: obtain a temporal collision probability between the moving objects according to the time coordinate values corresponding to the start frames and the end frames of the moving objects; obtain a spatial crossover probability between the moving tracks according to the spatial coordinate values passed by the moving tracks of the moving objects; obtaining the spatio-temporal redundancy of the moving tracks according to the temporal collision probability and the spatial crossover probability; and determining the synopsis ratio of the moving tracks according to the spatio-temporal redundancy.
