摘要:人脸识别在中国的发展可以追至二十世纪九十年代,到目前为止已经越来越趋于成熟,它覆盖了人工智能,模式识别,数学,数字图像处理等多门学科。该技术可用于身份确认,身份鉴别,访问控制,人机交互,安全监控等等,因其技术特征而使这项技术具有广泛的市场应用前景。本文主要要解决的问题是,从有复杂背景的图像中检测并分割出人脸,再与模板人脸进行相似度检测,确定模板人脸是不是存在与复杂图像中。主要工作分为两个部分:一是人脸的检测和分割,这一部分选用基于统计Adaboost人脸检测算法,利用opencv相关接口实现。二是在分割的人脸区域进行特征的提取,这里采用基于几何特征的算法,定位眼睛,鼻子和嘴角,利用这些位置构造特征向量,利用这些向量完成匹配。65261

Title Template-based complex adaptive image segmentation and Matching
Abstract
Face recognition in China's development can chase the 1990s,So far has become more and more mature.It covers pattern recognition, artificial intelligence, mathematics, digital image processing and many other subjects.The technology can be used for identity recognition, authentication, access control, security monitoring, human-computer interaction, etc..Leaving its technical features of this technology has a broad market prospect。In this paper, the problem is to be solved,The image from a complex background to detect and segment the face,Then the similarity with the template of face detection,Sure there is not a template face image with complex.Major work is pided into two parts: First, face detection and segmentation, this part of the selection based on statistical Adaboost face detection algorithm, using OpenCV related interface..Second, in the face region segmentation for feature extraction, where the use of algorithms based on geometric features, positioning the eyes, nose and mouth, the use of these locations feature vectors constructed using these vectors complete match.
