【摘要】 为了提高自动指纹识别系统AFIS(Automated Fingerprint Identification System)中指纹图像采集的质量,降低采集系统的实现复杂度,提出了一种基于新型半导体指纹传感器FPS200的指纹图像采集方案。并通过平滑滤波、锐化、二值化等算法对原始图像进行了增强处理。在不同的工作参数和采集条件下进行了实验。结果表明,该指纹采集系统可以简便可靠地获取指纹图像数据,并且通过图像增强处理能够得到较清晰的图像,适用于AFIS的各种后端处理。更多还原

【Abstract】 In order to enhance the quality of fingerprint image and reduce the implementation complexity of the image acquisition systemin AFIS(Automated Fingerprint Identification System),we propose a figerprint image capture plan based on the new fingerprint sensor chip-FPS200.And then the original image is enhanced by smooth filtering,sharpening,binarization.We use different parameters with the capture environment to experiment,the results show that the system can gain original fingerprint image simply and dependablely,and corresponding enhancement algorithm can be integrated into practical AFIS.更多还原
