1. A method for coordinating between separate image sensors, each imaging a mutual area of interest at a different imaging perspective, the method comprising the procedures of: designating at least one target point on a first image of an area of interest acquired via a first image sensor at a first imaging perspective; defining and characterizing a plurality of feature points on said first image in the vicinity of the designated target point; transmitting information associated with said first image over a data communication link to at least a second image sensor situated at a separate location from said first image sensor; and identifying said target point in at least a second image of said area of interest acquired by said second image sensor at a second imaging perspective, by implementing an iterative convergence operation towards the target point location in said second image, wherein said iterative convergence operation comprises: in a first iteration, locating in said second image the feature points corresponding to the feature points defined in said first image; in each subsequent iteration, locating in a subregion of said second image the feature points corresponding to a subset of the feature points defined in said first image, where said subregion is defined by the cluster of feature points located in the previous iteration, and where said subset of feature points decreases relative to the previous iteration; and when a termination condition is reached, establishing the remaining cluster of located feature points in said second image to represent said target point.
