摘要
将小波变换理论应用于图象边缘提取,提出了一种新的图象边缘检测算法。一种相对于(c_0,c_3)=(0.05,0.05)的对称尺度函数被用于二进小波变换,得到原图象的一个多分辨率表达式,再提取图象的边缘特征。实验结果表明,本方法是解决图象边缘提取的一个十分有效的模型。
A new image edge detection algorithm which utilizes the wavelet transform theory is proposed. A symmetric scaling function corresponding to (c0,c3) = (0.05,0.05) is used to perform the dyadic wavelet transform. The authors get a multiresolution image strategy and extract edges. Experimental results show that the algorithm is adaptive and capable for dealing with an image edge.
