Abstract:
1. A method implemented by at least one processing device, comprising: recording at a first resolution a first sequence of video images of a scene; determining from content of the first sequence of video images a presence of a target of interest within a first portion of the scene at a first time; recording at a second resolution, greater than the first resolution, a snapshot image of the first portion of the scene containing the target of interest at the first time; recording at the first resolution a second sequence of video images of the scene, the second sequence acquired after the first time but before a second time; determining a velocity and a direction of the target of interest from at least one image produced by a single stationary camera; predicting, based on the velocity and the direction of the target of interest, that the target of interest will be within a second portion of the scene at the second time different than the first time; recording at the second resolution a snapshot image of the second portion of the scene at the second time; and linking the snapshot image of the first portion and the snapshot image of the second portion to at least one of the first sequence and second sequence of video images.
