摘要

在分析产生大面积的眩光、反光的指针式仪表图像特征的基础上

利用高斯函数结合同态滤波对该类图像进行预处理

并在实验平台下仿真.通过实验仿真

能得到清晰的二值图

实验结果说明该方法是有效的.

Abstract

After analyzing the features of the images which glisten and have large area dizzy brightness

a new method is proposed.The reformative homomorphic filtering is combined with the function of Gauss

for the pretreatment of the images.Simulated by the experiment

clear binary images can be obtained.Experimental results show that the proposed method is effective.
