Microscopic roughnessThe accurate evaluation on the shear strength of rough rock joints has always been the pursuit of rock mechanics workers. In this paper, based on the MATLAB image processing technology, the joint surface contour was firstly numerically reconstructed. Then, the Gaussian smoothing ...

滤波器gaussian卷积smoothing滤波filter GaussianSmoothingFilter 高斯平滑滤波器 一、图像滤波的基本概念 图像常常被强度随机信号(也称为噪声)所污染.一些常见的噪声有椒盐(Salt &Pepper)噪声、脉冲噪声、高斯噪声等.椒盐噪声含有随机出现的黑白强度值.而 脉冲噪声则只含有随机的白强度值(正脉冲噪声)或黑强度值(负脉冲噪...
In this paper, we propose a novel energy efficient approximate Gaussian Smoothing Filter that provides better results over the conventional approach. The proposed design is implemented in Tanner EDA tool to obtain design metrics and modeled in MATLAB to get error metrics. Simulation results shows ...
