1. A method for operating an image processing system, comprising: processing a pixel or pixels of interest with the image processing system using a selected implementation of an image processing operation, the selected implementation being one of a set of available implementations for the image processing operation; obtaining calibration data; modifying the set of available implementations based on the calibration data so that the set of available implementations includes at least one previously unavailable implementation; and processing a subsequent pixel or subsequent pixels of interest with the image processing system after modifying the set of available implementations.
