摘要：

针对传统的红外图像对比度增强方法存在的运算速度慢、增强效果不佳的问题,提出了一种基于自适应传播机制的红外图像对比度快速增强算法。首先使用自适应传播机制求出红外图像的各种局部空间信息,然后对各种信息进行非线性拉伸调整,得到增强后的图像。最后,比较和分析了几种增强算法实验结果,证明了本方法快速高效的优异性质。

Abstract: To improve the speed and quality of conventional methods for contrast enhancement of infrared images,the authors described a fast approach for image contrast enhancement,based localized adaptive propagation rule.Firstly,the method used adaptive propagation rule to get local and global spatial information,then,using this in formation to non-linear enhances the image contrast.Experimental results of this proposed approach and other conventional method were compared and prove that this method run faster than other conventional approach,it's more effective than other method in enhancing image.
