利用帧积分法去除微光图像噪声研究
LOW LIGHT LEVEL IMAGE PROCESSING WITH THE METHOD OF FRAME INTEGRAL
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,帧积分法对光子噪声以及系统内部信息载流子产生与复合所引起的散粒噪声的抑制有十分有效的作用.
Abstract
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.
