| 摘 要： | 针对遥感影像中兴趣目标的分割与提取，考虑到遥感影像的模糊性和不确定性，提出了一种基于梯形模糊映射的面向对象的遥感像模糊增强技术，该技术不仅突出了要提取的目标，而且也使原本模糊的边缘变得更为清晰。试验表明该方法是有效的。

| Abstract: | Image enhancement is one of the important image processing techniques for remote_sensing image.It is true that there exists a lot of methods of image enhancement,but most of them are heuristic and problem dependent.Each of them is just suitable for a given problem and purpose of application.In this paper,considering the ambiguity and uncertainty in grayness of image containing an object,an object_oriented method of fuzzy enhancement for remote sensing image is presented to well highlight an interested object of image and to restraint the background.Unlike the common method of fuzzy enhancement of image,a trapezoid_like fuzzy member_ship function is designed to transform the intensity domain to the fuzzy domain.In addition,it is not always necessary that the fuzzy membership of a crossover point must be equal to 0.5 in our method.This technique can not only highlight the interested object according to one's requirements and the feature of image but also make the blur edge of object clearer.The experiments show that the results are satisfactory. |
