Face image based age estimation is an approach to classify face images into one of several pre-defined age-groups. It is challenging because the aging variation is specific to a given individual and is determined by not only the person's gene, but also by many external factors, such as exposure, weather conditions (e.g. ambient humidity), health, gender, living style and living location. Age categorization...
In order to provide better information support and services for manufacturing informationalization, and provide technical information services for the process design, process information decision, manufacturing process modeling and simulation and product information management, etc., in the product manufacturing process, by using Web technology, database technology, modeling and simulation technology...
In this paper, we propose an IP address-based approach to track the growth of the Web for making a reliable and accurate estimate of the IP address usage. Our method uses a proper sampling of the entire IP address space, resulting in a significant reduction of effort to obtain an accurate estimate. A thorough analysis of the proposed improved Importance Sampling approach is presented. Based on the...
To get the video clips we need from the vast videos, it is necessary to seek an efficient method for video editing and combining. But there is much difficulty in nonlinear editing for videos such as MPEG-2 format. This paper proposes a method to edit multiple format videos including MPEG, AVI, WMV, VOB by DES technology. And we address an algorithm to realize the cancellation and recovery function...
It is an important knowledge management task to evaluate a user's domain knowledge in a knowledge community. We present a new domain knowledge representation method that considers both user-document associations and document-topic relevance. We provide three alternative user-document association models with varying syntactic and semantic inferences and two alternative document-topic relevance models...
Modern computer vision research consumes labelled data in quantity, and building datasets has become an important activity. The Internet has become a tremendous resource for computer vision researchers. By seeing the Internet as a vast, slightly disorganized collection of visual data, we can build datasets. The key point is that visual data are surrounded by contextual information like text and HTML...
Network coordinate (NC) which provides efficient distance prediction with scalable measurements, brings benefits to various network applications. Phoenix Network Coordinate system is a recently proposed dot product based NC system with high prediction accuracy and better robustness. In this paper, we discuss the neighbor selection policies for Phoenix and propose a modified Phoenix with hybrid neighbor...
Although geographic information systems (GISystems) have been widely used in both public and private sectors, geographic information is still not effectively used by common citizens for their everyday's life. A metropolitan spatial service infrastructure (MSSI) is a new vision to build a societal GIS allowing every citizen to create, share, and use geographic information and services. We propose our...
The rapid development of Internet technology brings people not only great convenience but also many potential safety hazards. This paper studied and implemented embedded Linux operating system first and then introduced the network topology and transmission mechanism of system and identity authentication protocol and key exchange protocol of platform, subsequently introduced the data encryption algorithm...
We introduce a text-based image feature and demonstrate that it consistently improves performance on hard object classification problems. The feature is built using an auxiliary dataset of images annotated with tags, downloaded from the Internet. We do not inspect or correct the tags and expect that they are noisy. We obtain the text feature of an unannotated image from the tags of its k-nearest neighbors...
Online credit evaluation system is the foundation for the establishment of trust and for the management of risk between buyers and sellers. This paper studies the contents of credit evaluation system on both sides of online business interaction. We find out that the current system is too general and is difficult to be put into practice, then we propose a new model based on analytic hierarchy process...
We describe a method to retrieve images found on Web pages with specified object class labels, using an analysis of text around the image and of image appearance. Our method determines whether an object is both described in text and appears in a image using a discriminative image model and a generative text model. Our models are learnt by exploiting established online knowledge resources (Wikipedia...
Research and application of Web text mining is an important branch in the data mining. Web is the biggest information system currently. Now people mainly use the search engine to look up Web information. The problem of getting reliable rate and comprehensive rate is increasingly convex, and it is very difficult to mine data further. Now the search engine can hardly provide individual service according...
Google Maps is a free Web mapping service application and technology provided by Google that offers Web map service. Ajax is a new technology based on asynchronous communication between a client Web browser and a back-end server, allowing Web applications to request and receive data without ever reloading the page. Google Maps is the popular application that uses Ajax technology. With Ajax, this paper...
A well-built dataset is a necessary starting point for advanced computer vision research. It plays a crucial role in evaluation and provides a continuous challenge to state-of-the-art algorithms. Dataset collection is, however, a tedious and time-consuming task. This paper presents a novel automatic dataset collecting and model learning approach that uses object recognition techniques in an incremental...
The paper introduces the experiment of traffic information service based on probe car system in Beijing of China. It is sponsored by JETRO of Japan, for the protection of environment like deceasing energy consuming and air pollution. About 2000 taxies running on roads send GPS and other status data in real time to the data base of the taxi dispatching center, which transmits the data to the data base...
