In this paper, we propose an improved method for recovering 3D facial shape from a single image. We use level set method to solve the Eikonal equation obtained from the method of shape from shading (SFS). However, the results are not usually usable due to the concave-convex ambiguity problems inherent to SFS. In order to overcome the concave-convex ambiguities of SFS, we find out the boundary of the...
XML-SNMP based network management model is essential parts of the network management infrastructure. It is generally recognised that there are two problems remained unsolved for this kind of model. These two problems are load balance of the XML manager and the potential bottleneck of the XML/SNMP gateway. This paper presents a novel XML-template based approach to tackle these two problems. We developed...
In order to improve the robustness and accuracy of the credit evaluation model, we study on individual credit risk, select a statistical method of Logistic regression and a non-statistical method of neural network BP algorithm, which are most frequently used methods by domestic and foreign banks. Furthermore, we separately improve these two methods to some degrees, using Clementine tools to build...
With the development of network technology, all kinds of events will be shown up as news rapidly on the World Wide Web. Internet users read the news and some of them give their comments online. It is important for crisis public relations, government decision-making and news impact analysis to understanding the netizens' comments on the news events. Due to the huge amount of news and comments on Web,...
There exists a certain dynamic relationship between the gasoline's rotation speed, power and torque. For the example of Citroen C4-1.6L engine which existed in laboratory centers of our college, we have studied the combustion process which rises with rotation speed at a constant torque by means of some experiments. By comparing with steady-state conditions, we have analyzed such the parameters as...
The environment of patient ward is very important to the recovery of gynaecologic surgery. There are three main factors about the environment of patient ward: temperature, humidity and the number of free-swimming bacteria which existed in air. These three factors are all have an influence on the recovery of gynaecologic surgery. In this paper, we have analyzed how these three factors to affect the...
