On the basis of analysis and comparison of their strengths and weaknesses, each method can find its applied occasion. With energy method, we can conveniently control the precision of the objective surface and add boundary constraints for preserving the models global geometric continuity, but this method is very time-consuming.

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.

纵使美国社会有千般不好，一个能够使欧普拉诞生，能够使欧普拉发挥影响力，能够使普罗大众从电视萤幕前偶尔探头看看白纸黑字的书本的社会，看起来似乎就是比我们有了更多「向上提升」的可能。

An annual is best known as a plant that completes it's life cycle in a single season. Hardy annuals can survive cold temperatures and some light frost, while tender annuals cannot tolerate cold temperatures and should be planted only after there is no more danger of frost. Half-hardy annuals can tolerate some cold temperatures, but are usually killed by frost. Annuals make excellent space fillers for the perennial garden.

一年生植物最显著的一个特点就是它在一个季节内完成它的生命轮回，耐寒的一年生植物能够在低温和轻微霜冻的条件下生存，但是幼嫩的一年生植物不能忍受低温，他们只能在没有霜冻危险的条件下种植，半耐寒型一年生植物能够经受一些低温条件的考验，但是通常他们因为霜冻死亡，一年生植物能够为多年一成不变的庭院创造一个很出色的空间。
