For the sake of the person of the examination candidate for election whether a district is a real person or not a picture, also will make use of the formula(6) cast shadow the training( test) characteristic space inside to this candidate a that cast shadow the district is a minimum distance to makes use of a person39。s face or not person39。s a district) binary system picture definition is, among them It( x, y) With the It1( x, y) respectively is a bright degree for with front an inside pixel( x, y).The St is a current an inside skin color pixel to gather, the t is a worth [ in limit in to makes use of appropriate limit technique pute 9 ] .The acceleration that be used as a process handles, we make use of the operation( morpholoical operations) that appearance learn( top) with link the position analyzes, simplifying the picture Mt. make use of the PCA examine person39。s skin district, skin color is not suitable for in the person an use of to act information can away with this weakness the sake of the precision, after the skin color divides into section, consider the skin color district of the containment action , the action information of the bination skin color model leads a binary system for a containment scene( person39。s improves an accurate for examining, we announce such as the skin color model [ 1,6 ] with PCA [ 7,8 ] these already of the technique knot puts together. skin color classification The examination skin color pixel provides a kind of examination with follow the facial and dependable method in pass many that sees the machine resemble a RGB picture not only include color but also gets bright degree in containment, so this color space is not the best color to examine the skin color pixel [ 1,6 ] bright a three positions for distinguishing analyse a color pixel, can move bright Gauss for of color distributing is in a small chromatic color space large groupsly, and can passing first 2 cent department to look , pass a 2 Gauss models can look like this skin color model, among them average value with change as follows: m=(r ,g ) 其中 r ＝ N1 ??Ni ri1， g ＝ N1 ??Ni gi1 （ 1） ? ＝ ?????????? （ 2） Once set up to like the skin color model, a positions facial and simple method in person is match the importation picture to look for facial color in middleman in picture a pixel of the primitive picture were changed into the chromatic color space, then distributing with the skin color39。s face candidate for election districts first, bine exploitation PCA technique to judge the real person a , make use of the characteristic technique( eigen － technique) follow to confirmed person39。s face that follow has not yet the proof, for example arm with hand. In this text, we put forward a kind of according to PCA solid contemporaries an examination with follow the method, that method is an activity to make use of a,such as figure,1 show resemble machine to examine with identify the person kind of method from two greatest steps posing:Person an examination with person39。02) According to the method of the edge useds for the edge that follow a picture preface row, but these edgeses is usually the boundary line of the main , because were musted shine on with the light at the color by the on the trail of object the term descends to display the obvious edge changes, so these methodses will fall among the color with the variety that light shine addition, be a background of picture contain very obvious edge,( follow the method) dependable result in very difficult this type of method that a lot of cultural heritages all involve e from the Kass et the snake form rate of exchange motion [ 5 the achievement of ] see the scene of to acquire from included various the noise of varieties solid the hour the resemble the machine of, therefore many systems is very rare to dependable person39。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 person39。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 telemunication meeting, invader check system etc. 1 preface Seeing the signal of handles many applications, for example owing to the munication can see the telemunication 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 can39。 realize solid contemporaries face examination with on the trail of a kind of method. These kinds of method regard main position 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 person39。未來(lái)的工作是我們將進(jìn)一步發(fā)展這種方法，通過從被檢測(cè)的人臉區(qū)域 種萃取臉部特征來(lái)為臉部活動(dòng)系統(tǒng)服務(wù)。被提議的這種方法是實(shí)時(shí)進(jìn)行的，且執(zhí)行的過程分為兩大部分：人臉識(shí)別和人臉跟蹤。用 偽代碼來(lái)表示平衡 /傾斜處理的持續(xù)時(shí)間和攝像機(jī)的定位。在表 2 自己品母國(guó)。使用這個(gè)距離向量，就能控制攝像機(jī)中定位和平衡 /傾斜的持續(xù)時(shí)間。為了跟蹤人臉，位于被跟蹤人臉的特征向量和 K 個(gè)最近被檢測(cè)的人臉之間的歐幾里德距離是用 obj＝ argkmin||Wold－ Wk||， k＝ 1，?， K，（ 8）來(lái)計(jì)算的。投影區(qū)域的檢驗(yàn)是利用人臉類和非人臉類的檢測(cè)區(qū)域內(nèi)的最小距離，通過公式（ 7）來(lái)實(shí)現(xiàn)的。對(duì)于 M 個(gè)訓(xùn)練（測(cè)試）人臉圖像，特征向量W i＝ [w 1， w 2，?， w M’]用 w k＝ u kT? i,k=1,?， M（ 6）來(lái)計(jì)算。因此，為了計(jì)算的可行性，與其為 C 找出特征向量，不如我們計(jì)算 [YTY]中 M個(gè)特征向量 vk和特征值 ? k， 所以用 u k＝kY?vk*來(lái)計(jì)算一個(gè)基本集合，其中 k＝ 1，?， M。為了計(jì)算 M 的直交向量，其中該向量是用來(lái)最佳地描述人臉圖像地分布，首先，使用 C＝ M1 ??Mi1?i? i
