一种基于DTW的动态笔迹识别算法
A Dynamic Handwriting Recognition Algorithm Based on DTW
摘要
Abstract
With the rapid development of mobile internet technology,smart phones,tablet PCs and other mobile devices have also been widely used.Mobile devices in the online shopping,online payment,transfer and other aspects of a convenient and fast features,online e-commerce trading volume is growing,leading to mobile platform e-commerce information security risks become more prominent,information security technology on the mobile platform Application is becoming more and more important.Biometrics-based identity authentication has been widely used to overcome many of the shortcomings of tra-ditional authentication methods.Handw riting handw riting is one of the important areas of biometric identification,because of the collection device is simple,easy to collect,security and other advantages,by the majority of users accepted.A dynamic handwriting recognition algorithm based on DTW is proposed to identify handwriting handwriting on mobile platform.The algorithm combines the slope of the path in the Fast DTW algorithm to ensure the recognition efficiency,and improves the recognition accuracy by aligning the starting end points when the relaxation time is bent.The experimental results show that the error rejection rate(FRR)and false acceptance rate(FAR)of the algorithm are 4.5% and 1.5% respectively,and the recognition efficiency and recognition accuracy are improved compared with the classical DTW algorithm and FastDTW algo-rithm.关键词
