夜视图像的彩色融合技术及其进展

Color Fusion Technology for Night Vision Imaging and its Progress

介绍了夜视彩色图像融合算法的研究进展 ,着重分析了以接近自然色彩为目的的MIT法以及我们提出的线性组合法、基于视觉拮抗模型的非线性图像增强与线性组合法结合的混合结构法 ,给出了若干组场景下各方法的微光与热成像的彩色融合图像以及微光彩色融合图像 ,显示出良好的目视观察效果 ,提出了需要进一步研究的问题和关键技术。

The progress in research on algorithms for night vision color image fusion is introduced, with emphasis on the analysis of the MIT method which aims at nearly natural color, as well as the linear composite method and the mixed architecture method comprising the non linear image enhancement based on visual antagonism model and linear composite method, both of which are proposed by us. Both the color fusion images in low level light and thermal imaging, and the low light color fusion images made by various methods under several sets of sceneries are given, with good visual observation results. The issues and key technologies needed for further development are proposed.
