In this paper, we propose a novel graph based spatiotemporal saliency detection method which models eye movements using random walk with restart. The method is executed in superpixel domain and unify low level features and high level features into the framework of random walk with restart. The boundary prior, as a high level feature, is employed to obtain a boundary prior based restarting distribution...
Change data capture (CDC) is an approach to data integration that is used to determine and track the data that has changed so that action can be taken using the change data. However, the state of art of change data capture (CDC) in the context of document-oriented NoSQL databases is not mature. Therefore, it is urgent to require a NoSQL CDC solution. Although some manufacturers of NoSQL databases...
We develop an efficient general-purpose blind/no-reference image quality assessment (IQA) algorithm that utilizes curvelet domain features of phase congruency values and local spectral entropy values in distorted images. A 2-stage framework of distortion classification followed by quality assessment is used for mapping feature vectors to prediction scores. We utilize a support vector machine (SVM)...
Bibliometrics is a research field that analyzes the bibliographic material quantitatively. It provides efficient methodologies for classifying the information of a scientific discipline. This paper presents an overview of the most productive and influential authors and institutions in finance by using bibliometric indicators. The information is classified by using several global rankings that consider...
In this paper, a novel biometric authentication scheme is proposed, which combines zero-knowledge proof, - protocols and bit commitment scheme. The remote server compares biometric template using committed values, this can keep privacy of user's biometrics. To the best knowledge of us, this is the first scheme which uses - protocols as a basic tool to implement biometric authentication. Compared with...
IT infrastructure is highly complex and changeable for reacting to business update with market change. Unfortunately, change is not always successful. Managing change effectively and reducing the negative effects of day-to-day operations has become one of the most important tasks in IT service management. Beyond recording all configuration items used in the provision of operational services, analysis...
Web Services (WS) is a popular way of implementing SOA-based software, which gained rapid progress. Several Web Services are usually combined to create new services by a mechanism named Composite Web Service. Composite Web Service is one of the most important components to WS.Composite Web Services testing is a difficult topic in WS testing. In this paper, we present a regression testing method for...
The most issue is designing the fitness function of the chromosome when Generic algorithm is been used for gcalculating the minimal attribute reduction in rough set theory. But with the existed fitness function of the chromosome, the one that the value of the fitness function is larger might not be an attribute reduction. So the optimization candidate attribute reduction might not be the minimal attribute...
IT services need an automatic and flexible ability to react to dynamic changes in their environment. Managing change effectively and reducing the negative effects of day-today operations has become one of the most important tasks in IT service management, which require hiring highly skilled IT professionals with correspondingly high labor costs. There is a challenge to select, implement and integrate...
SIP flow management should respect the specific characteristics of SIP protocol applied in multimedia or telecom services for meeting stringent quality of service (QoS) requirement. The specific characteristics include explicit session structure for correlating a series of SIP messages, stringent response time required by real-time applications, extra overhead imposed by SIP message retransmission,...
