Abstract
A method for displaying off-screen target indicators in motion video comprising the steps of receiving motion video containing a series of individual video frames, selecting a target object within a selected video frame by choosing selected target object pixel space coordinates, and determining whether the selected target object pixel space coordinates are within the selected video frame. Upon determining that the selected target object pixel space coordinates are within the selected video frame, the method updates a dynamical system model with the target object geographical coordinates, longitudinal target object speed, and latitudinal target object speed. Upon determining that the selected target object pixel space coordinates are not within the selected video frame, the method calculates estimated target object geographical coordinates at time t using the dynamical system model. The method then calculates final values in the video field of view at which to draw a target indicator.
