Enhancing two-dimensional contrast images rendered from three-dimensional streak tube imaging lidar (STIL) data

A method is provided for enhancing two-dimensional contrast images rendered from three-dimensional STIL data. Briefly, the rendered contrast image data is scaled based on a mean intensity value of all pixels of data therein, stretched to a predetermined dynamic range, modified to compensate for jitter and CCD array effects associated with the STIL camera system, normalized using an exponential decay function that describes contrast intensity roll-off associated therewith, and has a histogram clip routine applied thereto.
