基于小波多尺度分解的印鉴图像配准

Registration Methods of Seal Imprint Identification Based on Multiscale Wavelet Analysis

论文提出了一种基于小波多尺度分解的印鉴配准方法。用一维环投影向量的循环移位来代替二维图像的旋转。利用小波分解结果,采用大尺度特征向量来进行相关性分析,实现图像配准。其主要优点是算法具有很强的抗干扰性并且具有广泛的适用性。

In this paper,a Registration method of two seal imprints is proposed for Chinese seal identification.The seal imprint is divided into rings and the intrinsic features are extracted.Therefore,the cyclic shift of one-dimensional ring projecting vectors is adopted instead of rotatation of two-dimentional images.Then the Multiscale Wavelet analysis is processed.The registration result of high precision obtained by the experiment shows that the proposed approach is of adaptability and reliability.
