摘要
高斯型拉普拉斯(LoG)算子采用高斯滤波器平滑图像。高斯滤波器需要控制截止频率来改变滤波的效果,本文主要分析高斯低通滤波器和LoG算子的各种特点,通过计算机模拟来分析含噪声图像的滤波后对LoG算子边缘检测的影响。
Gauss-Laplace(LoG) operator uses Gaussian smoothing filter.Gaussian filter controls the cut-off frequency to change the effect of filtering.This paper mainly analyzes the characteristics of the Gaussian low-pass filter and LoG operator,and the effect of LoG operator edge detection is analyzed by computer simulation in noisy image filtering.
