Abstract
A method is provided that includes receiving from a camera, video depicting a scene having a center bounded by first and second horizontal edges. The scene also includes an identified object of interest (OI) having a region around the identified OI and a motion vector representing a location, and an amount and at least a horizontal direction of movement. The method also includes calculating from the location of the identified OI, a distance of the identified OI from either or both of the horizontal edges of the scene, and in which the first horizontal edge is in the horizontal direction of movement and the second horizontal edge is opposite the horizontal direction of movement. And the method includes causing an increase or decrease in speed of the camera in the horizontal direction of movement based on location of the identified OI relative to the first/second horizontal edges.
