This paper proposes a person authentication system using second minor finger knuckles, i.e., metacarpophalangeal (MCP) joints, for door security. This system acquires finger knuckle patterns on MCP joints when a user takes hold of a door handle and recognizes a person using MCP joint patterns. The proposed system can be constructed by attaching a camera onto a door handle to capture MCP joints. Region of interest (ROI) images around each MCP joint can be extracted from only one still image, since all the MCP joints are located on the front face of the camera. Phase-based correspondence matching is used to calculate matching scores between ROIs to take into consideration deformation of ROIs caused by hand pose changes. Through a set of experiments, we demonstrate that the proposed system exhibits the efficient performance of MCP recognition and also show the potential possibilities of second minor finger knuckles for biometric recognition.

一种实用的人认证系统,使用第二小指节来保证门的安全

本文提出了一种使用第二小指节即掌指(MCP)关节的人认证系统,以确保门的安全。当用户握住门把手并识别使用MCP关节图案的人时,该系统会获取MCP关节上的手指关节图案。可以通过将摄像机连接到门把手上以捕获MCP接头来构造建议的系统。由于所有MCP关节都位于相机的正面,因此只能从一个静止图像中提取每个MCP关节周围的感兴趣区域(ROI)图像。基于阶段的对应匹配用于计算ROI之间的匹配分数,以考虑到手姿势变化引起的ROI变形。通过一组实验,
