It solves the problem that the unitary contour presentation can not correctly extract face contour in a face image which suffers from scale, rotation etc. The definition of the internal and external energy function is provided. At the same time, the global matching algorithm and local matching algorithm is given. The experiment shows that this presentation and the accompanying matching algorithm can be used to extract the face contour very well. So the image segmentation can be implemented by using it.②By analyzing the recognition principle of PCA method, we can conclude that the face images coming from different surrounding consist of different face image space. This is the essential reason that makes the generality of PCA method worse. Also, we give a measurement means to measure the distance from different face image space, so we can analyze face image space more conveniently.③We also construct various scale models and rotation pose models to detect the scale and rotating angle of face image to be recognized. The experiment results show that the detecting precision is very high. So it is good for face image feature extraction and face image representation.④Similarly, we construct local feature models of face image and utilize them to detect the local feature of face image. At the same time, we put forward a novel face image local feature detection algorithm, locating step by step. The experiment results show that this method can accurately detect the location of local face feature in a image.⑤A novel face image presentation model, dual attribute graph , is put forward. Firstly, it utilizes attribute graph to present the face image, then exact the local principal component coefficient and Gabor transform coefficient of thc pixels which corresponds to the nodes of the graph as the attribute of the nodes. This representation fully makes use of the statistical characteristic of the local face feature and utilizes Gabor transform to present the topographical structure of face image. So DAG has more general property.⑥Based on the DAG presentation, we give a DAG matching function and matching algorithm. During the design of the function and algorithm, the noise factor, e. g., lighting, scale and rotation pose are considered and tried to be eliminated. So the algorithm can give more general property.⑦A general face image recognition system is implemented. The experiment show the system can get better recognition performance under the noise surrounding of lighting, scale and rotation pose.

本文在上述研究的基础上，取得了如下主要研究成果：①构造了一个通用的人脸轮廓模型表示，解决了由于人脸图象尺度、旋转等因素而使得仅用单一轮廓表示无法正确提取人脸轮廓的问题，并给出了模型内、外能函数的定义，同时给出了模型的全局与局部匹配算法，实验表明，使用这种表示形式以及匹配算法，能够较好地提取人脸图象的轮廓，可实际用于人脸图象的分割；②深入分析了PCA方法的识别机制，得出不同成象条件下的人脸图象构成不同的人脸图象空间的结论，同时指出这也是造成PCA方法通用性较差的本质原因，并给出了不同人脸空间距离的一种度量方法，使用该度量方法能够直观地对人脸图象空间进行分析；③构造了各种尺度模板、旋转姿势模板以用于探测待识人脸图象的尺度、旋转角度，实验结果表明，探测精确度很高，从而有利于人脸图象特征提取，以及图象的有效表示；④构造了人脸图象的各局部特征模板，用于人脸图象局部特征的探测；同时提出了一种新的人脸图象局部特征探测法---逐步求精定位法，实验结果表明，使用这种方法能够精确地得到人脸图象各局部特征的位置；⑤提出了一种新的人脸图象表示法---双属性图表示法；利用属性图来表示人脸图象，并提取图节点对应图象位置的局部主成分特征系数以及Gabor变换系数作为图节点的属性，这种表示方法充分利用了人脸图象的局部特征的统计特性，并且使用Gabor变换来反映人脸图象的拓扑结构，从而使得双属性图表示法具有较强的通用性；⑥在双属性图表示的基础上，给出双属性图匹配函数及匹配算法，在函数及算法设计过程中，考虑并解决了光照、尺度、旋转姿势变化等因素对人脸图象识别的影响，使得匹配算法具有较强的通用性；⑦设计并实现了一个通用的人脸图象识别系统，实验结果表明，该系统在图象光照、尺度、旋转姿势情况下，得到了较好的识别效果。

In a remote mountains, have the hunter with a first-rate marksmanship, one day, he hunts into hill, going, encounter a batch of wolves suddenly, the hunter lifts a gun to want to hit, be in this is wolf mouth conversation, it is OK that you hit me, but I have a condition, the hunter says then you say, the wolf says you can hit me 3 guns, if you are hit,do not die me, do you make I ate you OK, it is OK that the hunter listens to have very much confidence ground says, the hunter opens two guns repeatedly, see a wolf still stand over, the hunter is very amazed, opened the 3rd gun again then, wolf or station are over there, the hunter sees him be defeated pull, say to the wolf you can eat me to pull, the wolf looks say you should take off the dress pull me eating you, the hunter agrees to pull, take off the dress then pull, when taking off last briefs, the wolf sees pull make off at once, running, the wolf encounters one countrywoman, countrywoman asks a wolf, you run what, the wolf says the thing that bets on hill to be pulled, did not think of to there still is a gun below him, countrywoman listens, the 2nd gun that tells a wolf him but very fierce, 10 years ago, I was hit by him one gun, cut still does not have heal now.

导读：在一座深山里，有一个枪法非常好的猎人，有一天，他进山打猎，走着走着，突然遇到一批狼，猎人举枪便要打，就在这是狼开口说话，你打我可以，但我有一个条件，猎在一座深山里，有一个枪法非常好的猎人，有一天，他进山打猎，走着走着，突然遇到一批狼，猎人举枪便要打，就在这是狼开口说话，你打我可以，但我有一个条件，猎人说那你说吧，狼说你可以打我三枪，如果你打不死我，你就让我吃了你可以吗，猎人一听很有信心地说可以，猎人连开两枪，一看狼还站在那里，猎人很吃惊，于是又开了第三枪，狼还是站在那里，猎人一看自己输拉，就对狼说你可以吃我拉，狼一看说你应该把衣服脱拉我在吃你，猎人同意拉，于是把衣服都脱拉，脱到最后一件内裤时，狼看到拉撒腿就跑，跑着跑着，狼遇到一村妇，村妇问狼，你跑什么，狼就把山上打赌的事说拉一遍，没想到他下面还有一棵枪，村妇一听，告诉狼他的第二棵枪可很厉害呀，十年前，我被他打了一枪，伤口现在还没愈合呢。
