The results show that the velocity increases when the neighbor radius grows,and decreases when the excitation threshold increases.
结果表明,行波波速随邻域半径增大而增大,随激发域值增大而减少。
This paper proposes an improved method on the basis of a half-neighborhood operator.
该文在半邻域法的基础上提出了一种基于自适应阈值选择的图像边缘提取算法,在判断某一像素点是否在边缘上时,以该像素点为中心,选取3×3的区域为研究对象,求出该区域的最大、最小、均值像素值及标准差,在选用标准差为其阈值的同时,还考虑人的视觉对于灰度分辨能力的限制。
In this paper, a new method is presented to introduce the conception of fuzzifying semi-open sets and we define the concepts of the fuzzifying semi-neighborhood system based on it.
本文用新的方法引入fuzzifying半开集的概念;利用此半开集概念确定fuzzifying半邻域系。
