红外起伏背景的广义平稳特性研究

STUDY ON WIDE-SENSE STATIONARY PROPERTIES OF INFRARED CLUTTER BACKGROUND

研究了计算大气云层背景图像集的样本均值、自协方差及 2 σ误差区间的方法 ,并在此基础上 ,针对实际的红外图像进行了大量的实验测试 .实验结果表明 。

In the paper, the mean and auto-covariance are first computed and estimated by means of average across the IR cloudy-background clutter image sets. On this basis, the 2 error ranges of them are also computed. Then, experiments on the real IR images are run. The experiment results show that the statistics based on IR cloudy-background clutter images is wide-sense stationary.
