一种新的基于NSCT域的遥感图像增强算法
New NSCT-based remote sensing image enhancement algorithm
摘要
Abstract
In order to solve the problem appearing in the process of image enhancement, such as, pseudo-Gibbs phenomenon and low contrast, a new threshold algorithm is proposed which is on the basis of NSCT domain. On the one hand, this proposed algorithm makes use of NSCT' s shift-invariance to prohibit the pseudo-Gibbs phenomenon, on the other hand, deals with NSCT's coefficient by combining fuzzy contrast and spatial frequency to improve contrast and get better visual effect. The experimental results show that the proposed algorithm gets better results than the traditional method and owns some certain value in practical application.关键词
