快速人脸检测技术在证件照中的应用与研究

Application and Research of Fast Face Detection Technology in ID Photos

在人脸识别应用中,经常会应用到证件照图像,要对其进行识别处理,就先要进行人脸检测.与普通图像不同的是,有些证件照图像本身已经接近人脸检测结果要求,有些可能是半身照,证件照的许多共有特征可以在人脸检测过程中起到很好的辅助判别作用实现快速检测,并不需要使用复杂的算法就可以取得较好的检测效果.经过研究与实验,本文针对证件照图像设计了一种基于肤色分割的快速人脸检测算法,利用证件照的特性取得快速准确的检测结果.

ID photos are often applied into the application of face recognition, and before we do the recog- nition processing, we first need to do face detection. Unlike ordinary images, some ID photos are almost close to face detection results requirements, some may be bust shots, many common features of ID photos can be able to assist finishing fast detection in the process of face detection, and it does not need complicated algorithm to achieve good detection effect. Through research and experiment, this paper aims at designing a fast face detection algorithm based on skin color separation for ID photos, and uses ID photos＇ features to achieve fast and exact detection result.
