摘要
人脸检测作为人脸信息处理中的一项关键技术,成为近年来人工智能领域内的一项研究热点。文章简要介绍了人脸检测的理论基础,讨论了人脸检测的预处理、阈值检测和边缘检测三种常用的方法;重点研究了直方图阈值分割和边缘检测这一关键技术,并在MATLAB环境下进行了仿真。通过结果可以看出,只有将边缘检测技术和其他方法结合起来才能达到理想的检测效果。
Face detection has became a research hotspot in the field of artificial intelligence in recent years,which is used as a key technology in face information processing.The paper briefly introduces the theoretical basis of face detection,and then the article describes the three commonly used methods such as pretreatment,threshold detection and edge detection.Focus on the key technologies of face detection—histogram threshold segmentation and edge detection,then simulation in the MATLAB environment.The results show,that only a combination of edge detection techniques can achieve the desired results.
