【摘要】 根据列车轮对图像的特性,主要探讨了基于小波分析的原理,并基于 Bubble 二进小波函数进行图像多尺度边缘提取。利用边缘相关判据排除噪声边缘,取边缘响应极大点作为配准控制点。实验结果显示,本方法能够很准确地提取出图像的主要边缘信息。更多还原

【Abstract】 According to the properties of train wheel image,in this paper the concept of wavelet transform is intro- duced.The proposed approach applies wavelet transform to extract a number of feature points as the basis for registra- tion.And multi-scale edges of image are obtained.Each selected feature points is an edge point whose edge response is the maximum within a neighborhood.The results show that the edge has good property and can be used for matching of images.更多还原
