中文摘要：

现有夜视系统主要是依靠图像增强器来改善夜间视觉图像的质量，成本比较高。借助Zadeh—X变换理论，利用DirectShow开发平台实现了暗视觉视频底层图像的挖掘。通过2级灰度平坦化分析，该实现方法使图像层次更清晰，对暗视觉视频底层图像的挖掘取得了较好的效果，可以作为传统夜视系统后端处理的有效工具。

英文摘要：

The existing night-vision system is mainly by virtue of image intensifier to improve image quality, but costs too much. Based on the Zadeh-X transformation, night vision video image mining was actualized by DireetShow develop platform besides. The new method can acquire tile images that there are much betterment at level of images and the quality of image that is appereeived by human vision through two gray spectrum flattening analysis, achieving better results in the night vision video images mining. It will be an effective tool for post processing of the traditional night vision system.
