Paper Abstract

This paper presents a new nonuniformity correction (NUC) algorithm based on scene-matching for linear scanning focal plane arrays, especially for the rapidly developing TDI scanning arrays. The algorithm bases on matching every two adjacent images in which most parts reflect the same scene. The response relationship between detectors can be calculated from the matched part-pairs. Then it can be used to complete the nonuniformity correction and to adapt the drift of the nonuniformity with variations in environmental temperature. The experiments on real image sequences demonstrate the accuracy and robustness of the proposed algorithm.
