基于手掌形状的身份模糊识别

Fuzzy Recognition of the Identity Based on Palm Shape

人与人的手掌形状存在差异,利用这一特征进行身份识别,与指纹和虹膜识别相比,具有数据采集简单、设备成本低等优点。在这种识别系统中,为了防止身份的误识别及漏识别,必须解决好现场手掌形状参数的采集、识别码生成及身份判断等问题。本文介绍了解决上述问题的研究结果,给出了手掌参数的采集、数据库的建立以及用模糊识别技术进行身份判断的实现方法,并说明该方法在小范围群体中使用,能够达到较高的识别可靠性。

There are many differences of palm shape of people. Progressing identity recognition using this characteristic,compared with fingerprint or iris,has a lot of advantages, such as simple data gathering and low cost. In this type of identity recognition system,it is important to gather parameter of palm shape,to create recognition code and to estimate identity in order to prevent the problems of missing and skipping. The result of solving the problems is described in this paper. The method to gather the parameter of palm shape,to create the data-base and to recognize the identity with fuzzy technology is provided. In the colony of small range, this method of identity recongnition would achieve higher recognition reliability.
