摘要
本文首先简要总结了手写签名认证研究的进展情况,然后提出基于插值的改进的局部相关分析认证方法。该方法通过插值克服了书写板采样频率低导致的相关系数下降的问题,并改善了书写过程固有的时间轴弯曲。本文还提出了一种确定阈值的新方法。
In this paper,a conscious survey of researches on signature verification is presented first,and then an improved regional correlation algorithm based on interplotation is described. This algorithm overcomes the unfavorable dropping of correlation coefficient due to the low sampling rate of the graphic tablet and solves the non- linear time axis distortion problem.This paper also presents a new method to determine the decision threshold.
