摘要:
这篇文章提出了复杂背景条件下,实现实时人脸检测和跟踪的一种方法。这种方法是以主要成分分析技术为基础的。为了实现人脸的检测,首先,我们要用一个肤色模型和一些动作信息(如:姿势、手势、眼色)。然后,使用PAC技术检测这些被检验的区域,从而判定人脸真正的位置。而人脸跟踪基于欧几里德(Euclidian)距离的,其中欧几里德距离在位于以前被跟踪的人脸和最近被检测的人脸之间的特征空间中。用于人脸跟踪的摄像控制器以这样的方法工作:利用平衡/(pan/tilt)平台,把被检测的人脸区域控制在屏幕的中央。这个方法还可以扩展到其他的系统中去,例如电信会议、入侵者检查系统等等。
1.引言
视频信号处理有许多应用,例如鉴于通讯可视化的电信会议,为残疾人服务的唇读系统。在上面提到的许多系统中,人脸的检测喝跟踪视必不可缺的组成部分。在本文中,涉及到一些实时的人脸区域跟踪[1-3]。一般来说,根据跟踪角度的不同,可以把跟踪方法分为两类。有一部分人把人脸跟踪分为基于识别的跟踪喝基于动作的跟踪,而其他一部分人则把人脸跟踪分为基于边缘的跟踪和基于区域的跟踪[4]。
基于识别的跟踪是真正地以对象识别技术为基础的,而跟踪系统的性能是受到识别方法的效率的限制。基于动作的跟踪是依赖于动作检测技术,且该技术可以被分成视频流(optical flow)的(检测)方法和动作—能量(motion-energy)的(检测)方法。
【Abstract】:
This article put forward complicated background term next; realize solid contemporaries face examination with on the trail of a kind of method. These kinds of method regard main composition analysis technique as basal. Facial examination in person for realizing, first, we want to use a skin color model to act the information with the some (such as: Posture, signal, expression of eyes).Then, the usage PAC technique examines these drive the district that examine, from but judge a real position. But person's face follows according to the is several in the virtuous (Euclidian) distance of, among them the is several to reign in the virtuous distance in past drive on the trail of person's face with recent drive the person who examine the characteristic space inside of the a. Useding for a for following resembles the controller the work in such way: Make use of equilibrium/ tilt to one side (pan/ tilt) the terrace, examine drive of person a district controls at hold the act central. This method cans also expand to go to in the other system, for example telecommunication meeting, invader check system etc.
1 preface
Seeing the signal of handles many applications, for example owing to the communication can see the telecommunication meeting that turn, for disable and sick person service of the lips reads the system. In up many systems that mention, the facial examination in person drink to follow to see to can't lack necessarily of constitute the part. In this text, involve the some solid of person a district follows the [1 - 3 ] .By any large, according to follow the angle different, can is divided in to follow the method two types. Reach a the part of people follows person's face is divided into according to identify on the trail of to drink according to act of on the trail of, but other a the part of people then follows person's face is divided into according to edge of on the trail of with on the trail of [that according to district 4].
According to the on the trail of that identify is really with the object identifies technique is basal, but follow the function of the system is the restrict of the efficiency to suffer to identify the method. According to the on the trail of of the action is a method to depend on to examine the technique in the action, and that technique can be been divided in to see flow( optical flow) with the method that act the — energy( motion - energy).
