内指节纹识别方法研究

Research on Recognition Method of Internal Finger Knuckles

在当今信息化社会中,诸多场合都需要身份认证,目前最有效的方法是生物识别技术。作为一种新兴的生物识别技术识,指节纹识别有自己独特的优势,具有纹理丰富、用户接受度高、采集设备成本低等特点,拥有广阔的发展前景。相对于外指节纹,内指节纹的研究成果较少,但内指节纹还有对比度高、可以和手形等手部特征结合组成精度更高的多模态识别系统的优点,因此,针对传统的内指节纹进行研究,并将主要算法进行对比。

In today's information society,identity authentication is required on many occasions,and the most effective method at present is biometrics.As an emerging biometric recognition technology,knuckle pattern recognition has its own unique advantages,with rich texture,high user acceptance,and low cost of acquisition equipment,and has broad development prospects.Compared with the outer knuckle pattern,the inner knuckle pattern has less research results,but the inner knuckle pattern also has the advantage of high contrast and can be combined with hand features such as hand shape to form a more accurate multi-modal recognition system.Therefore,Research on traditional inner finger knuckles and compare the main algorithms.
