MFP (Mobile FingerPrint)

A short time ago, the study of contactless fingerprint authentication gained appeal among biometric researchers. Contactless fingerprint systems offer various advantages, such as ease of capture and affordability, over conventional fingerprint identification systems, which demand that the user's finger make direct contact with the sensor.The Mobile FingerPrint dataset (MFP dataset) contains thumb and index fingerprint images. The finger is placed in front of the mobile camera without any contact, and the camera should be placed in front of the finger at approximately 14 cm to capture the entire fingerprint modality. Images are taken without light conditions and in a free position.

近期，无接触式指纹认证技术在生物识别研究界受到了广泛关注。相较于传统指纹识别系统，该系统通过用户手指与传感器的直接接触进行识别，无接触指纹系统在捕获便捷性和成本效益方面具有显著优势。《移动指纹数据集》（MFP数据集）包含拇指和食指的指纹图像。在采集过程中，手指无需接触放置于移动相机前方，相机应置于距离手指约14厘米处以捕捉完整的指纹模式。图像在无光照条件下和自由姿态下进行拍摄。
