微光图像特征分析及图像融合技术研究

LOW LIGHT LEVEL IMAGE CHARACTERISTICS AND IMAGE FUSION TECHNOLOGY 

从微光图像的成像过程、灰度分布和像素空间与时间相关性等几个方面对微光图像特征作较系统的分析 .用信息容量这一示性参数来表征高相关图像灰度层次的丰富程度 ,这与视觉效果达到了很好的一致 .通过分析这些特性 。

The characteristics of low light level (LLL) image were analyzed in aspects of imaging process gray level distribution and correlativity of picture element in space and time of LLL image. Richness of gray level of highly correlative image was expressed using information capacity,which agrees greatly with the effect of vision evaluation.It is of momentous guidable significance for study on LLL multi spectrum image fusion technology by analyzing these characteristics.
