Patent Images

1. A method comprising:

  • receiving a set of successive images for a given area from an image data source via a communication network, wherein the set of successive images comprises a first image captured at a first time, a second image captured at a second time, and third image captured at a third time, and wherein the given area comprises a plurality of sectors;

    determining, for each respective sector of the given area, (i) a first likelihood of change between the first image captured at the first time and the second image captured at the second time, (ii) a second likelihood of change between the first image captured at the first time and the third image captured at the third time, and (iii) a third likelihood of change between second image captured at the second time and the third image captured at the third time;

    evaluating the first, second, and third likelihood of change for each respective sector of the given area to identify any sector of the given area that exhibits a given type of change; and

    outputting, to a client station via the communication network, data indicating that the given type of change has occurred at each identified sector of the given area.
