人体的“身份证”

生命科学的一个重要组成部分——生物识别技术，发现了人体上的“身份证”，不仅限于手指，而且在手掌、脸上、眼睛、嘴唇、大脑、血液以及嗓音、气味和步态上也都有“身份证”。

人体生物特征识别技术在安防领域中的开发应用（上）

本文对人体生物特征——声纹、指纹、眼纹、味纹、脸纹、掌纹等自动识别技术的工作原理、特点、国内外开发应用现状及其在银行金融、电子商务、机场、海关等安防领域中的应用范围、实例、优越性和前景作了较全面系统的介绍与评述。

Research on Face Tracking in Community Monitoring System

This paper proposes a block Mean-Shift algorithm based on target real-time update and LBP texture features, through the target update improves the accuracy of target tracking, enhances the local character of the target through the target block, so as to improve the robustness of algorithm based on skin color backgrounds. And then analyze the Mean-Shift algorithm cannot recover quickly lost target tracking defects, and its improvement by combining the frame difference method.
