摘要
在公共安全领域的软件开发中,有大量的人脸识别业务需求。Python语言具有功能强大、运行高效的优点,现已成为人脸识别技术应用开发的主流技术。与指纹识别、虹膜认证等技术相比较,人脸识别技术可以在被识别对象无感知的情况下对其进行远程身份识别,具有其他生物识别技术不可替代的优势。人脸识别技术具有几何特征、模型特征、统计特征和智能特征。人脸识别技术的流程可分为人脸检测、特征提取和人脸比对三个步骤。本文介绍在Windows环境下构建基于Python的软件开发平台,并附以Web方式实现从图像中检测出人脸位置及大小的Python程序代码。
In the field of public security software development,there are a large number of face recognition business needs.Python language has the advantages of powerful function and high efficiency,and has become the mainstream technology of face recognition technology application development.Compared with fingerprint recognition,iris authentication and other technologies,face recognition technology can recognize the remote identity of the identified object without perception,which has the irreplaceable advantages of other biometrics.Face recognition technology has geometric features,model features,statistical features and intelligent features.The process of face recognition technology can be divided into three steps:face detection,feature extraction and face comparison.This paper introduces how to build a software development platform based on Python in Windows environment,and how to realize the python program code to detect the position and size of human face from the image by web.
