人脸检测与人脸识别
(1)人脸检测(Face Detection)
人脸检测(Face Detection)是指在输入图像中确定所有人脸(如果存在)的位置、大小、位姿的过程。人脸检测是自动人脸识别系统中的一个关键环节。
(2)人脸识别
人脸识别细分为两类,一类是回答我是谁的问题,即辨认(Identification),另一类是回答这个人是我吗?即确认(Verification)。显然,用于Identification模式的识别系统对算法的运算速度的要求要高于Verification模式的识别系统。
(3)区别于联系
从人脸自动识别技术所依据的理论来讲,人脸检测与人脸识别都是模式识别问题。
人脸检测是把所有的人脸作为一个模式,而非人脸作为另一个模式,人脸检测的过程就是将人脸模式与非人脸模式区别开来。
人脸识别是把每一个人的人脸作为一个模式来对待,不同人的脸属于不同的模式类,人脸识别的过程是将属于不同人的脸归于各自的模式。
换句话说,人脸检测强调的是人脸之间的共性,而人脸识别则要区分不同人脸之间的差异,二者同属于模式分类问题。
-Face Detection and Face Recognition
(1) Face Detection (Face Detection)
Face Detection (Face Detection) is all in the input image to determine the face (if it exists) of the location, size, position and orientation process. Automatic Face Recognition Face detection is a key component of the system.
(2) Face Recognition
Face recognition is subdivided into two categories, one who is answering my question, namely identification (Identification), the other is to answer this person is me? Is recognized (Verification). Clearly, the identification system for Identification mode of operation speed of the algorithm is higher than the requirements of the Verification pattern recognition system.
(3) different from the contact
From the automatic face recognition technology is based on the theory in terms of face detection and face recognition are pattern recognition problem.
Face detection is all the human face as a model, rather than the face as another mode, face detectio
