摘要
利用 Bubble小波函数 ,通过 Mallat算法可对印鉴图像进行小波分解和边缘检测 ,在此基础上 ,提取由傅里叶系数所导出的形状特征 ,然后利用神经网络分类器进行训练 ,继而实现印鉴的自动鉴别。
The wavelet resolution and edge detection are made to the image of seal imprint by the use of Bubble wavelet function and Mallat algorithm.Based on the result,an automated verification system of seal imprint is realized with the help of both the characteristics of appearance derived from Fourier coefficient and the training through neural net classifier.
