摘　　要：针对目前红外场景校正算法存在的鬼影和参数时间漂移,提出基于中间均衡直方图的单幅图像校正算法。算法将场景校正的思想运用到图像列上,通过计算每一列的中间直方图算法来替代原始列的直方图。实验结果表明,算法优于总变差算法,具有简单快速,易于工程应用的优点。To overcome the problem of ghosting artifacts and parameters drifting over time in current IR scene, a non unifotmity correction algorithm via midway equalization histogram is presented. Firstly the idea of scene correction is used to the image columns, and then the midway equalization histogram of the column is computed to take the place of original cumulative histogram. Experimental results show that the proposed algorithm is superior to the total variation algorithm and has advantages of simpler ,faster and easier to engineering application.
