In this paper, we propose a method that can handle the color correction of a large collection of photographs simultaneously and automatically via robust reference selection. The method does not use any particular model to handle the errors on the photographs, but corrects all kinds of errors caused by changes of viewpoint, large illumination variations, gross pixel corruptions, and partial occlusions...
Nowadays, the harmful blue-green algae blooms on lakes or streams threaten the daily life of millions of people in China. In this paper, we demonstrate the sensor network system we built on Lake Tai for the surveillance and cleanup of the algae blooms which is at work in Wuxi City, Jiangsu Province. We designed the sensor device and algorithm to monitor the algae bloom and estimate the bloom area...
Botnet has become a prevalent platform for malicious attacks, which poses a significant threat to Internet security. Recently, botnets are inclined to utilize HTTP to route their command and control (C&C) communication instead of using the protocol Internet Relay Chat (IRC). And these web-based C&C bots try to blend into normal HTTP traffic, which makes them more difficult to be identified...
In order to solve task scheduling and load balancing problems of distributed search engines, a GNP-based scheduling strategy for distributed crawling and a load balancing method are proposed in this paper. Internet distance estimating mechanism is adopted as a replacement for large-scale network distance measurement, which not only improves response speed of the system, but also reduces loads on WAN...
Interest in scalable vector graphics (SVG) is increasing rapidly. Based on XML, SVG can be easily used on Web application. But the progressive transmission technology of SVG has still not been developed well. To address this, we propose a multi-resolution storage model, progressive transmission mechanism and along with some implementations for the SVG data. In the model, a SVG file is partitioned...
XML (extensible markup language) has become the standard of data representation and data exchange in the Internet. A highly efficient management on XML documents has become an urgent problem. In this paper, we introduce the development of a native XML database management system, called dasiaXSQSpsila (XML storage and query system), which provides the ability of the storage and query for XML documents...
The access control service has been an important orientation in the security research. In this paper, the essentiality of access control service in the E-Commerce Web was analyzed; the relative technologies were introduced at the same time. And through describing a concrete collaborative e-commerce platform, a detailed description of how to design and implementation of access control systems were...
This article analyzes the current Web graphic processing technique, and then it puts forward a new model of object grouping database and technology of rapid graphic refreshment based on the incremental data. Later on it discusses collaborative graphic editing technology to organize GIS data more effectively and improve graphics interaction processing efficiency under network environment.
Network monitoring, prediction and diagnosis are of great importance for network administrators to manage their network. But direct measurement of network characteristics is sometimes infeasible. Network tomography comes out as an effective solution for this problem. It makes inference for network internal parameters with end-to-end measurement, and introduces probabilistic reasoning idea into network...
The evaluation for Web service is essential to select Web services from many candidates, but current evaluation models evaluate Web service only by common service attributes, which can not meet the requirements of end users. We propose an evaluation model for Web service, which customizes reasonable attributes in different domains as evaluation factors, and computes the weights of evaluation factors...
Making use of the resources on the WWW fully and effectively has become important for more and more people. Based on this, we designed and implemented a prototype of a personalized intelligent navigation system, PINS. It assists users in finding and obtaining the information they are most interested in more efficiently. In order to gain portability, scalability, interoperability, reliability and good...
