摘要
生物识别技术属于一个大范围概念,其中应用最为广泛、发展最为成熟的就属于指纹技术。指纹技术在图像处理、特征提取、特征对比以及指纹图像采集方面都有涉及。指纹技术涉及多项领域,其中最基础、最重要的就属于指纹图像采集。不同的指纹图像传感器在应用中显示不同的优势,但也存在不同的局限性。就指纹图像传感器技术关键与发展趋势进行简单分析。
As a key component of biometric technology,fingerprint recognition is broadly used in authentication and identification. Fingerprint recognition includes fingerprint image acquisition,image processing,extraction and comparison of characteristics. Among them,fingerprint image acquisition is the most fundamental step for successful fingerprint recognitions. There are pros and cons for each fingerprint image sensor technology. This review briefly summarizes the key differences among different fingerprint image sensor technologies and provides a perspective on their future development.
