粗集理论作为一种新的用来处理不确定性问题的数学工具。本文提出了一种基于粗集理论的图像增强方法,首先建立了基于粗集的等价关系和相应的划分集合,然后得到了基于粗集方法的图像平滑框架,并提出了基于粗集理论改进的图像增强的具体算法实现。本文方法的增强效果与传统方法相比较,具有更清晰的边缘和细节,并且算法简单易于实现。
Rough set theory as a new mathematical tool to deal with the problem of uncertainty. In this paper, an image enhancement method based on rough set theory is proposed. Firstly, the equivalence relations and corresponding partition sets based on rough sets are established. Then, an image smoothing framework based on rough sets method is proposed and an improved method based on rough set theory is proposed The image enhancement of the specific algorithm to achieve. Compared with the traditional method, the enhancement effect of this method has clearer edges and details, and the algorithm is simple and easy to implement.
