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.

This error can be as much as 10 C, depending on melt viscosity and flow rate. Normally, this is usually ignored as most extruders are more interested in comparative readings than absolute ones, but for the chemical reactions like cross-linking or foaming, a more exact value may be needed, and the amount of shear heating may need to be known. It is a relative simple thing to do - when the machine is to be shut down, stop the screw without reducing speed or barrel conditions and watch the drop in melt temperature over the first 10-20 seconds, or until it begins to level out again.
通常在大部分关注相对读数的挤出机上,这些偏差可以忽略;但如一些挤出反应如交联、发泡对反应温度要求精确,剪切产生的热量需要知道,有一个相对比较简单的办法:但关闭机器的时候,并不降低主机转速或者筒体温度,在第10-20秒时,或者直到熔体温度达到平衡时,观察熔体温度下降了多少。
