摘要

采用小波变换中的多分辨率分析方法

从仪表盘图像中提取出纹理清晰、具有不同空间分辨率、不同方向的边缘子图像

再用自适应滤波和数学形态学的方法对提取出的垂直细节图像进行形态运算

滤除无用的信息

定位最终的仪表参数区域.

Abstract

A new segmentation algorithm

based on wavelet multiscale analysis and mathematical morphology for locating the parameters of meter dial plate

is presented.By this algorithm

the edge components of different spatial resolutions and directions are acquired

the useless information is filtered and the last region of parameters of meter dial plate is located.
