微光图像
1.
The degradation of low-light-level image mainly depends on sensitivity,non-linearity and noise of detectors.
微光图像的退化主要取决于探测器的灵敏度、非线性和噪声。
2.
As the noise of low-light-level image can be removed efficiently and low-light-level image quality can be improved by low-light-level video real-time image processor, which has quality of super speed and real time, observation distance of low-light-level video observation system becomes far.
微光视频图像实时处理器以其具有的高速实时处理优点，可以有效地消除微光图像噪声，改善微光图像的像质，从而提高了微光视频观察系统的观察视距，这无论是在军用和民用上都有很广泛的使用价值。
3.
For the characteristics of infrared images for the target image focused on the distribution of gray,low-light-level grayscale image is relatively uniform distribution,a image fusion method is proposed in this paper,that is extracting infrared thermal targets firstly,and then fused to low-light-level image as the background.
针对红外图像中目标图像灰度分布集中,微光图像灰度分布相对均匀的特点,提出了一种先提取红外图像中的热目标,然后以微光图像为背景进行图像融合的方法。
