| 摘 要： | 针对煤矿井下岩层监视监控系统中图像边缘检测的问题,提出了采用小波变换进行煤矿井下岩层图像的边缘检测处理.综述图像边缘检测的方法,分析了基于小波变换模极大值的图像边缘检测方法.即首先将图像进行多尺度分解,以获得对图像不同结构特征的描述,进而在各个尺度下通过观测其小波系数模的变化规律检测出不同细节成分的边缘特征.研究结果表明,基于小波变换的图像边缘检测算法能够较好地检测煤矿井下锚杆钻孔内图像中的细节特征,取得了明显的效果.

| Abstract: | According to the problem of image-edge detection in the terrane monitoring system in coal mine underground,a way of using wavelet transform in image-edge detection processing is brought out.At the beginning of the paper the way of image-edge detection in generally is summarized,and then the way on the basis of maximum module of wavelet transform is analyzed.The first step is to de-compose the image in multi-size in order to describe the different structure character,according to observe each module of wavel... |
