摘要
在微光成像中 ,迭加在图像上的时空域噪声 ,不仅限制了系统可工作的最低照度 ,而且使显示图像具有随机蠕动颗粒闪烁的外观。图像处理技术能够提高图像质量 ,增强微光成像系统作用距离。实验证明 。
In the low light level image processing,the time and space domain noise in the signal not only limits the lowest illuminance of the system but also make the image show random glitter. The quality of the image and the operative distance of the system can be enhanced by the image processing. It testified that photon noise and particle noise can be well controlled by the method of frame integral.
