研究利用二维小波变换的模极大与法向角来检测图像边缘的方法。与采用传统方法进行比较,本方法得到的边缘不仅较完整、对噪声不敏感,而且具有单像素宽度,定位精确。

It is researched in this paper using the modulus maxima of 2D wavelet transform and normal angle to detect image edges.Compared with traditional methods,the method used in this paper proved to be relatively complete,insensitive to noises,with single pixel...
