1. A method for providing real-time registration of a camera array, the method comprising the steps of: applying a mapping function to register features among images captured by respective cameras in the array, the mapping function being expressed, at least in part, using a set of parameters; providing an initial calibration to the camera array; identifying parameters associated with the initial calibration; selecting a subset of the set of parameters for adjustment, the selected subset of the set of parameters having a relatively large contribution to errors in registration that occur subsequent to the initial calibration as compared with non-selected parameters; and adjusting the selected subset of the set of parameters in order to correct the errors so the camera array is substantially returned to the initial calibration.
