基于模糊逻辑的指纹与手形加权信息融合技术

为解决脱皮、有伤痕等低质量指纹识别困难、识别率低及稳定性差问题。提出手形作为指纹识别的辅助手段，采用模糊综合的身份识别方法，将指纹和手形进行加权信息融合，通过仿真实验，表明此方法实用、有效，能提高系统的识别率及稳定性。可广泛应用于刑侦、金融等对安全有严格要求的领域。

Fusion Technology of Weighted Information from Fingerprints and the Shape of Hand Based on Fuzzy Logic Theory

In order to solve the problem of difficulty, low efficiency and instability of identifying the fingerprints with inferior quality because of desquamating or scar, this paper brings forward the technique of utilizing the shape of hand as the subsidiary method to identify fingerprints. By introducing the method of fuzzy integrated identification, the information of fingerprints and the shape of hand are weighted with fusion technology. Emulational experiment shows that this technique is practical, and efficient. It can improve the efficiency of identification and stability of the system. This technique can be widely used in police and banking industries which have strictly high demand for safety.
