normal shock diffusion

A shock-diffusion equation with local coupling term is presented,where an inverse diffusion(shock)is performed to sharpen edges along the normal directions to the isophote lines(edges),while a normal diffusion is done to remove noise and artifacts(“jag-gies”)along the tangent directions on the contrary.

提出了带有局部耦合项的冲击扩散方程,其沿着等照度线(边缘)的梯度方向实施反向扩散(冲击)以锐化边缘;相反地沿切线方向实施正向扩散以去除噪声和锯齿伪像。

This thesis introduces a new method that uses the method of normal diffusion to analyse the regulation of fault distribution.

本文在分析故障分布规律的基础上,提出用正态扩散的方法对故障分布规律进行估计的新方法,理论证明,把正态扩散估计方法用于对故障分布的分析,可提高估计精度,具有较强的实用价值。

The paper illustrated the rational method of choosing the width by the normal diffusion principle and the adνantage of choosing the center factor by clustering.

说明了根据正态扩散的择近原则确定ＲＢＦ网络中规划因子的合理性，也说明了在训练样本数目大时用聚类方法确定中心参数的优越性。
